That is an incoherent conception of "equity". I don't really see how you can consider the pursuit of equity not to involve things like opening up otherwise exclusive (e.g. medical treatment) options to under-resourced individuals. Equity is nothing more than the "to each according to their need" half of traditional Marxism. And from what I can tell no one really has a problem with the latter half -- all critiques I've heard focus only on the former.
