Race is neither an analog for culture nor economic status, FWIW.
There are people from every race that have a "disadvantaged background". No race has the market cornered in western society on "advantage" or "disadvantage", because race is a meaningless quality in a meritocracy.
Nonetheless, even when speaking of economic or social status, "equality" doesn't mean "equity." We don't have equity, nor in a society that values both individual liberty, egalitarianism, and personal responsibility do we desire such a thing. It is the "land of equal opportunity", not the land of "equal outcomes".
