Not really. The richest American, aka 1/330,000,000 is is the top 0.0000003030303%, and is non other than Elon Musk, according to Forbes, assume you're referring to rich Americans (which excludes Bernard Arnault and Carlos Slim Helu), followed by Jeff Bezos, Larry Ellison, Warren Buffett, and Bill Gates. All $100-billionaires. An amount so staggeringly higher than mere mortals that it does everybody a disservice to lump them in with mere millionaires. You may have heard of tech millionaire Linus Torvalds (net worth $50 million) or Urs Hölzle (Google; $10 million). The top 0.000003% have five orders of magnitude more money.

Everyone is closer to being a millionaire than any of the billionaires mentioned.

I found this visualization by MKorostoff very educational on just how staggeringly much money a billion dollars is. https://mkorostoff.github.io/1-pixel-wealth/
