IME these mechanisms are a natural outflow of how those with money and power delegate power or invest money.
I have friends with a private plane. I also have friends who are scrambling to make rent, among many other friends always worried about their next paycheck. When you put the two together, you’ll find they can’t really engage in conversation about their lives without extreme embarassment - the plane people could solve most of the immediate problems facing the paycheck folks with barely a dent in their lifestyle.
So the plane people end up around people they can talk about vacation spots with, and the paycheck people hang around people who are empathetic and participate together in mutual aid to get thru. Rarely do the paycheck folks become plane people (they’re too generous or focus on maximizing other aspects of their lives than income). Rarely do the plane people actually help the paycheck people, except indirectly.
Inequality is embarrassing. Our society is embarrassing. That there is no safety net and basic needs being met being demanded by everyone from the poor to the richest of the rich can ONLY happen because they don’t interact. I see a huge backlash coming and it will not hit equally, or fairly. No society can continue like this without breaking down.
