4% of 5m is 200k; not a high level FAANG TC
Also different tax rates for investment vs income: 200k taxed at 30% is easily L6 level compensation. And if you're comparing to L6 anywhere outside of US it's easily L7.
Also: these amounts are declining. Except perhaps in AI.
In my experience, those numbers are low for the US. This is about accurate: https://www.levels.fyi/companies/google/salaries/software-en...
200k investment income * 0.7 * 2 = 280k income from labor.
300k investment income exceeds what you get on a 400k wage.
And you can probably get the tax on investment income down from that 30%, even to 10% sometimes, if you're willing to move (which you would have to do for a 400k job even if you're CEO at a large company anyway)
