As of 2021, 47.9% millenials in US own homes. So "new feudalism" has ~50% aristocracy rate (compare: 2-3% in times of real feudalism). This is probably partially due to increasing urbanization and higher life expectancy (alive grandfathers = no inherence).
Gini index remained quite stable over last few years, at least in English-speaking countries: https://data.worldbank.org/indicator/SI.POV.GINI?end=2018&lo...
"We should take legislative action to reduce inequalities" is legitimate political stance. "New feudalism" or "capitalism collapse" is bullshit.
