I don't think her philosophy is sound. You cannot advocate unregulated capitalism in a society where people don't start on equal footing.
Just because you are comfortable on middle-upper class doesn't mean you can't be objective about this things. That some kids are born into wealthy families and some are born in sub-Saharan Africa and forced to mine minerals for the former's iPad until they are 15 and keel over is undeniably wrong. But it's what arises from capitalism.
Equal rights for by definition inequal beings is what smart guys have tried to put into constitutions.
