This is all dead on.
It’s a bit late for anyone not to have figured this out yet, but the skeleton key to understanding American conservatism is this: At bottom, it lacks absolutely any moral or ideological underpinning beyond the reactionary protection of moneyed white men—of their station, their wealth and power, and their egos. Its supposed ideas and abstractions are just a framework for spasmodic lashing-out against anything that can be interpreted as a threat to rich white dudes. It likes supply-side economics because the supply side is made of rich white dudes. It likes tax cuts because the taxes are mostly cut for rich white dudes. It likes cops and soldiers because cops and soldiers uphold a social order with rich white dudes at the top. It likes “traditional family values” because social, economic, and sexual dominion over women are the most traditional family values of all. It likes “Make America Great Again” because rich white dudes used to roll through society and over everyone else with even greater impunity than they do now. All of these things are just proxies for reiterating, over and over and over, forever, the power and security and primacy of rich white dudes.
