Equality of what? There’s hardly a more confusing philosophical question. This is my attempt at sorting things out. I apologize for the length of this post, but there’s a lot to digest.
Equality of resources
A well-known problem with theories that focus on equality of resources is that different people need different resources because they have different abilities and different needs. Someone may need more food (in terms of calorie intake) because she has a physically demanding job, or may need more education than the average person because she has a brain dysfunction making it difficult for her to read or remember. Someone with a physical handicap may need expensive tools such as a wheelchair – and therefore more resources compared to a person not suffering a handicap – in order to have the same capability or opportunity to realize freely chosen goals as that other person.
The latter is an important point which I’ll come back to later on: you can’t just think about resources in isolation; you’ll have to consider which purposes these resources serve. Even if different people have the same purposes, they need different amounts of resources to achieve these purposes (and when they have different purposes, the need for unequal resources is even stronger). Hence, equality of resources seems to be an inadequate theory of equality.
A standard reply by resource based theories of equality is to count someone’s abilities (such as the ability to walk) as resources and try to equalize those as well. In our example, the handicapped person would then have equal resources when she has more money than average and just enough money to compensate the loss of resources resulting from her handicap. So it looks like equality of resources is a theory that can be salvaged.
The problem with this rescue is that not all abilities can be equalized by way of the redistribution of resources. Certain handicaps can be reasonably compensated by way of extra (financial or other) resources; paralysis may be one of them, especially given the most recent breakthroughs. But other handicaps can’t. A blind person for instance will probably never have equal abilities, no matter how much extra money or tools she gets. Her loss of eyesight is a loss of resources that can’t be fully compensated by other, equivalent resources.
Another problem with this attempted rescue of the equality of resources theory: there’s no good reason to limit abilities to physical ones. Talents are also abilities, and if you insist that all abilities are resources that should be equalized as much as possible then you’ll have to explain how to equalize talent. It seems very difficult if not impossible to supply extra resources to the less talented so that they end up with equal resources compared to the more talented. Like in the case of many physical abilities, a lack of talent can’t be compensated by way of extra resources.
So the attempt to rescue resource theories by including abilities in the pot of resources looks like it’s bound to fail. Resource theorist could reply that abilities and talents should be viewed as commonly owned resources. And, indeed, no one deserves her talents or most of her abilities; those are largely a matter of luck. Hence it’s not silly to view them as commonly owned. A talented person using her talents only for her personal benefit seems to be making an unjust use of her good luck. If abilities and talents are viewed as a common resource, then equality of resources could be achieved by giving those with few abilities and talents a right to use a share of the abilities and talents of others. However, this solution to the problems faced by resource theories creates another problem because it seems to imply the slavery of the talented (in the words of Dworkin). A talented person will find that she is less able to realize her freely chosen goals compared to another, less talented person, and equality of resource is justified, if at all, by the fact that it allows people to have an equal ability to realize goals. We thereby reverse the initial problem faced by resource theories, and put the burden of equality of resources on those with more abilities rather than on those with less abilities. That’s not a solution; it’s shifting the problem elsewhere.
If we can’t equalize all abilities, maybe equality should be limited: we can try to equalize as many abilities as possible and as far as possible. We can’t equalize a blind person’s abilities, but we can go some distance towards equality (we can offer Braille, improved transportation infrastructure etc.). We can’t equalize the abilities of a person without any talent, but we can offer this person some resources that help her attain a decent level of abilities.
Equality of preference satisfaction
But then we’ll have to say something more: we can’t talk about abilities in isolation (like we can’t talk about resources in isolation); we have to answer the question: abilities to do or be what exactly? One possible answer, and in fact the traditional liberal answer is: whatever people think they should do or be. Then we’re essentially talking about equality of preference satisfaction. Welfare is another word for preference satisfaction and the theory that tries to equalize people’s preference satisfaction is usually called equality of welfare. The purpose is then to distribute resources and improve abilities in such a way that people’s preference satisfaction (or welfare) is equal, or rather as equal as possible given people’s different and often fixed abilities to do things.
However, this theory faces a similar problem as equality of resources: people don’t just have unequal abilities and talents but also unequal preferences (preferences in the sense of the ability to do or be something). And those different preferences require different amounts and types of resources. As such, that’s not a problem. The problem is that some people have preferences that requires very large amounts of resources in order to be satisfied, and these extraordinary preferences are often self-chosen. In this case, these people’s claim on others to the resources necessary for the satisfaction of their extraordinary preferences seems hard to justify, especially from an egalitarian viewpoint. Society is under no obligation to redistribute resources to these people in order to guarantee equal preference satisfaction. Caviar fans have to work for their own money. And if they won’t, well then they have to adapt their preferences rather than appeal to society to redistribute the resources they need for their preference satisfaction. This is one reason why equality of preference satisfaction also seems to fail as a valid theory of equality.
However, we shouldn’t always force people to take care of their unequal or extraordinary preferences by themselves or to modify their preferences if they can’t. Some idiosyncratic preferences are closely connected to people’s identities, and in some cases those may not be self-chosen. Indigenous tribes may consider it essential to their unchosen identity that they have an exclusive right to a certain part of a country’s territory and resources (such as hunting grounds and the stock of fish or deer). There may even be self-chosen preferences that merit the same treatment. People with a preference for artistic expression may have a good claim to transfers of social resources (in the form of subsidies for the arts for instance). In those cases, equality of preference satisfaction does also apply to extraordinary preferences.
Still, notwithstanding these counter-examples, there are numerous cases of preferences requiring relatively large amounts of resources that those holding the preferences can’t produce themselves and at the same time can’t legitimately claim from society. Hence, equality of preference satisfaction does not seem a worthwhile goal.
And it’s not worthwhile for another reason as well. It’s not just that some preferences require unjustifiably large amounts of resources; some preferences are immoral. One can’t justify redistribution of social resources for the satisfaction of immoral preferences. Yet another argument against equality of preference satisfaction results from reflection about the term “preferences”. What is a preference? Is it every unreflected desire? Or rather only those desires an agent would pursue if she had the chance to rationally consider and evaluate all possible desires on the basis of all pertinent information? Do we want a drug addict and a bacillophobe to engage in preference satisfaction? And to redistribute social resources in such a way that they can in an equal manner compared to students and entrepreneurs?
Welfare theories may start off with equality and neutrality regarding preferences (the liberal premise), but because of the problems of morality and unreflected or irrational preferences, they quickly become paternalistic. Welfare theories, compared to resource theories, have the advantage of focusing not on instrumental values but on what ultimately matters to people, namely preference satisfaction. But not everything that matters to people, or that people think matters to them, should receive equal social concern or approval. Some things that matter to some people should not be encouraged from a moral point of view, let alone be subsidized. Other things don’t merit support from redistribution of resources because those things are irrational or self-chosen, expensive and not instrumental to other values such as identity. But once you have to decide which things that matter to people should or should not have a place in social policies that aim at equal preference satisfaction, you are likely to act in a paternalistic way and endanger another important value, namely freedom.
And even when welfare theories manage to remain neutral regarding preferences and don’t encourage or discourage certain preferences, they face the problem of comparing amounts of preference satisfaction across different preferences. Does a music lover, who has the resources to listen to music one hour a day, have an equal level of preference satisfaction as the American Indian who is able to hunt and fish freely and undisturbed whenever he wants? Are those things not inherently incommensurable? If so, how are we to achieve equality?
Equality of opportunity of preference satisfaction
Given the problems faced by preference satisfaction theories, one could assume that theories of equality should move to equality of opportunity of preference satisfaction. Rather than distribute resources so that people have equal preference satisfaction, we could limit distribution to those resource people need in order to have an equal opportunity to satisfy their preferences.
This move, however, doesn’t solve anything. We don’t want people to have the opportunity to act immorally, let alone the equal opportunity. And neither do we want them to have the equal opportunity to do expensive and extravagant things.
Equality of rights
Fortunately, there is a way out of this mess. We have to limit the range of equal opportunity, equal resources, equal abilities and equal preference satisfaction. A social and political regime should offer people an equal opportunity to a limited set of actions, functionings and beings, namely those that are necessary conditions for their human rights (see also here). People have equal human rights, and they should therefore have an equal opportunity to enjoy those rights in an equal way. Likewise, people should have the resources and abilities that are necessary for them to enjoy their rights, and their preference satisfaction should be a social concern and should be equalized only when those preferences are preferences for human rights (or for the conditions and resources for or the opportunities to enjoy human rights). (And yes, rights are preferences in the sense that they can be waived).
A problem faced by all theories of equality – including the one focused on or limited by equal human rights – is that people often squander their resources, their abilities, their preference satisfaction and their opportunities. They should be held responsible for their voluntary choices, and if those choices put them in a situation in which they have less resources, abilities, preference satisfaction or opportunities compared to others, then they don’t have a claim to more of those. That’s true for all resources, abilities, preferences and opportunities, except the resources, abilities, preferences and opportunities for human rights. If someone squanders her financial resources, she still has a right not to be poor. But if she loses her ability to acquire enough caviar, then she should take responsibility and not claim that society restores her resources. Similarly, if someone loses the ability to use her limbs through her own negligence, she still has a right to healthcare and mobility and a legitimate claim on society. However, if she thereby also squanders her ability to seduce men, she has no claim on anyone. If the same person has a preference for the enjoyment of a particular human right, but puts herself in a situation in which this enjoyment is impossible, she still has a claim to help. But her preference for fine chocolate made impossible through self-induced or non-self-induced diabetes doesn’t generate a legitimate claim on society. And, finally, if she squandered a good opportunity to education, she still has a valid claim to get some minimum level of education; if, however, she squandered a good dating opportunity, she doesn’t have a claim to the restoration of this opportunity.
Although the sidelining of responsibility is usually not a good thing, there are some practical advantages to it in this case. It’s often extremely difficult to detect responsible or irresponsible behavior. Seemingly irresponsible behavior may look like a voluntary choice but in reality it’s perhaps a choice that is determined by genetics, upbringing etc. Theories of equality which make responsibility and choice a precondition for equality – like luck egalitarianism for instance – face some challenging problems and a high risk of mistake.
Luck egalitarianism is yet another theory of equality. It demands that people’s unchosen luck (called brute luck, as opposed to option luck, the latter being the luck that people have when taking risks) be equalized. People should start life (in some versions of luck egalitarianism, adult life) with equal fortune, and equal fortune means equal resources, abilities and opportunities. They should be compensated for misfortune due to the lottery of birth. After that, all inequalities resulting from voluntary choice should be accepted by people themselves and by society.
Luck egalitarianism, like all other theories of equality discussed here (with the exception of equality of rights), is plagued by serious problems. Apart from the epistemological one (the difficulty of detecting voluntary choice and responsibility), there’s the problem of cruelty: why should we leave people to starve even if they have brought starvation upon themselves? They have, after all, a right not to starve. And then there’s the problem of intrusiveness: the epistemological problem will force luck egalitarian governments to enact KGB style measures in order to gain as much certainty as possible about responsibility. Other problems are discussed here.
The same solution is available here: instead of compensating people for all types of bad brute luck (but not option luck), we should compensate them for bad luck – brute or option – when this bad luck implies violations of their human rights or difficulties for future enjoyment of their human rights. People who are born paralyzed or who become paralyzed later in life – due to an accident which is or isn’t their own fault – all have a right to mobility and hence an egalitarian claim to social assistance. People who are born without talents or who squander their talents, don’t have such a claim because there is no right to have talent.
