One of Sam Walton's 5 children was a VC in solar energy before he passed away young, another owns Arvest Bank, and another is still running Walmart...

I also bet a majority of their wealth is still in that stock, as major sell-offs of insider holdings suggests a company may not continue to produce growing profits - which hasn't been the case. However, I'm sure some still have quite a bit with extremely capable money managers.

I would not call that wealth stagnating in the least bit.

I don't know how accurately their wealth is measured, but hiding a billion is not that easy so I will assume it's reasonably close. Anyway, ((15.7 / 15.3) ^ (1/15)) - 1 = 0.17% per year difference in wealth generation and spending per year for 5 people.

I expect they are all playing around with side investments of one sort or another, but they have had plenty of dividends to work with and little to show for it. It's not that I think the government would do all that much better, rather taxing society more to help maintain such wealth has zero benefit from what I can see.
