> mechanisms built into the system to prevent people from different classes to meet
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.

I wish you were right, but I think you are wrong. This article on poverty in ancient Rome suggests otherwise: https://en.wikipedia.org/wiki/Poverty_in_ancient_Rome "Their society may have consisted of a handful of wealthy individuals that made up 0.6% of the population, an army that made up 0.4% of the population, and the poor masses that made up 99% of the populace." I selected Rome because it's my understanding that this is one of the longest lived empires.
The facts for the Roman Empire are not clear, but it looks like massive inequality is the sad default mode for humanity. One might expect that as literacy and information sharing improved, it would be less tolerable by the populace for this inequality to persist. But it seems about as bad as ever. This may be due to the perception that rich people because they "earned" it, despite the fact that it seems patently obvious (to me at least!) that is not the case.
