> Traditionally America likes to pretend this kind of class contempt doesn't exist It just manifests as racism.
Most claims of racism in America are in fact classism. Very, very few people have actual dislike of others based on race. But a whole lot of people dislike people due to culture or class signals.
> Most claims of racism in America are in fact classism.
This is bald-faced racism denialism and makes a sweeping generalization. For example, the Trump administration is going after immigrants not for economic or class reasons but as a dogwhistle for their Floridian golf club members who don't like minorities of any sort and to appease a large section of the base of covert and overt racists generally. There is no logic in exiling and disappearing the low cost labor needed to product food, build homes, and do the terrible jobs that make civilization possible.. because it is mission of dumb people sabotaging themselves and others. The selective protection plus oppression and criminalization of undocumented people is grounded in the need to control a desperate, underpaid population to keep prices of agriculture, home construction, and restaurant prices lower than paying ordinary, livable wages to them.

You can't know this. And, it's leans towards false because of how propinquity works.
