That doesn't work out in practice. "The richest families in Florence in 1427 are still the richest families in Florence" https://qz.com/694340/the-richest-families-in-florence-in-14... The headline tells you what you need to know. The disruption thing is just a chimera to fool gullible people into thinking that rich people actually earned what they got and that the system is fair. It absolutely is not.

The richest families in the US are certainly not the richest ones from 1950 let alone 1427. The largest companies by market cap are Apple, MS, Google, Amazon, and FB... None of those businesses existed a generation ago let alone the technology that powers them or even their business models. At least some of the founders of those companies are immigrants. There is no reasonable extrapolation from wealthy families in Florence to "disruption is just a chimera to fool the gullible" in SV.

The three richest families in the US are (according to a simple Google search) the Waltons, Kochs, and the Mars. These three families were already in the 1950 very wealthy. I don't know enough to say whether they were among the richest, but for sure they weren't poor.
