It is not equality that is at stake in economic rights. Of course, the purpose of economic rights is the equal distribution of the material goods necessary for survival in a decent way. And in order to achieve such a distribution, some things have to be taken away from the rich who no longer have the freedom to do what they like with everything they own.
However, the problem that economic rights try to address is not that there is inequality or that some people have more than others or have too much of something. The problem is that some people do not have enough of certain necessities. Everything but these necessities can very well be unequally distributed.
