My take on Mexico is that it is effectively an Aristocrat/Peasant based system. Mexico works the way it does precisely because the ruling class there (mostly whites of Spanish descent) do not want the peones to get uppity. They do not want class mobility.
Liberals in America are trying to institute exactly this same sort of system in the USA, with the "elite" social classes of New York and Los Angeles ruling over us "deplorables" in flyover country.
Exactly.
