Don’t the unpaid loans get collected from the estate upon death, and the inheritors get whatever is left?

Still a tax dodge, but sounds like the wealth would reduce each generation?

I also still agree capital concentration is still occurring. Probably due to those loans getting used for excessive gains on the stock market. But those buys and sells would trigger capital gains tax.

Again not saying I’m ok with all this wealth concentration, just feels like a lot of nuance is missing here.
