I’m curious about your assessment of what fraction of wealth was inherited one and two centuries ago, and how you’re measuring the total stock of wealth.
Holding legal title to a thing is one extremely culture specific subset of wealth; being healthy, consuming goods and services is another, having status in your communities of choice is yet another, and control of the levers of societal power is yet another.
I am deeply skeptical of the claim that a larger fraction of titled wealth is now inherited than it was centuries ago, and I don’t see how you’d measure these other forms of wealth in a meaningful way.
