Right, but you're ignoring the loop-hole OP mentioned where you borrow un-taxed money then deduct it. Kill the loop holes.
So the only way to pay less tax is to surrender all your assets.

I included options because that's how ultra wealthy get their wealth from and it has market value of 0 so company could give lot of them.
Also anyone can get majority of your earning in stocks, not just ultra rich. Companies want to pay in stocks, and it's a win win for both, if there is a loophole.
(I'm happy to be wrong about this, since it seems unfair, but AFAIK this is how it works?)
This basically defers the taxes to a later date and charges you interest for 'em. Which might be worthwhile, depending on how quickly and reliably your capital is growing.
If you have a lot of assets you can just refinance your loan with more debt.
A loan should definitely be a taxable event and capital gains taxes should apply to rebase the value of the stock to the market value at the time the loan is taken out. Currently, very wealthy people use the loan dodge to avoid selling stocks and since the loan isn't paid off until death (usually), estate taxes wave their hands and any gains in the stock price go away, so that the next nepo generation gets to repeat the same dodge.
