Equality in the law, freedom of association, civil liberties, etc., etc. while technically in the US we "have" these freedoms, in reality we do not - we are subject to capitalism with regulatory capture, fines that unfairly punish the poor, so on. I'm on a phone, so I'm not typing out a dissertation.
Probably the best reference would be libertarian socialism or libertarian communism. The right wing Libertarian movement (which is dominant in the US) is really anarchi-capitalism, which is the complete opposite direction of left libertarianism (which is anti-capitalist).
Anyway, yes, there are a variety of ways freedoms are limited by simply being unable to afford things, or even being put into a position where you don't have the time to dedicate to those things. To me, that's fundamentally wrong.
