I think we're largely in that place right now with the black community. Institutional racism, as in legal doctrine that explicitly promotes racist goals, doesn't really exist. Eliminating the explicitly racist laws just isn't enough to solve the problem of racism, even within our institutions more broadly (although you could absolutely argue that the Senate as exists today enables this same sort of racism).

There's not a single country on earth that at one point had a legalized caste system where the legacy of such doesn't persist today.
