It is kinda interesting to see how much tech has overwhelmed the top rankings. I mean, “tech in the US has doing well” has been a thing all of my life, but over the years, it’s really crept up there. Almost everyone there is self-made wealthy in tech.

• Musk: manufacturing, fintech
• Page: tech
• Dell: tech (personal computers…again, manufacturing, not pure software)
• Bezos: tech (well…again, Amazon is also logistics now, though I do kinda think of it as a dot-com, not to mention being a cloud services provider)
• Brin: tech
• Zuckerberg: tech
• Ellison: tech
• Huang: tech (hardware, not software)
• Ballmer: tech
• Buffet: finance
• Ortega: fast fashion (and not in the US:Europe)
• Walton: retailing
• Arnault: luxury goods (and not in the US:Europe)
• More Walton: retailing
• Slim: Varied (and not in the US)
• More Walton: retailing
• Gates: tech
• Zhao: fintech/cryptocurrency (not in the US:China)
• Peterffy: fintech
• Bloomberg: finance, fintech

I mean, outside of Musk not fitting into pure tech, Waltons doing retailing, Buffet being a famous investor, and maybe Bloomberg, depending upon how you classify him, being finance, it’s all tech now. Like, that’s where the big economic growth has happened. The non-tech stuff is outside the US: two Europeans in luxury goods and retailing, and a Mexican in a huge conglomerate.

And in the US, only the Waltons are on there due to simply inheriting a shit-ton of multigenerational wealth.
