> In fact the conversion rate between them is about 20. A wealth tax of 1% is equivalent to an income tax of 20%.
Sure, but you actually have to work for continued income. Wealth accumulates with no input once established.
Wealth has the ability to increase (capital gains) without having to pay tax until it changes hands, whereas when income increases it is immediately taxed at a higher rate. Additionally, wealthy people can use securities as collateral for near zero interest lifetime loans which also bypass having to pay income tax.
There is little evidence that wealthy people actually borrow for income in any significant way. For example, this paper[0] finds that borrowing only accounts for 1-2% of economic income among the top 1%.
This makes sense. Borrowing for income in most scenarios is strictly worse financially than recognizing conventional income if you actually do the math. Wealthy people are optimizing for financial outcomes, not avoiding taxes per se.

This is just Internet mythology. The IRS would go after such arrangements very quickly - the IRS has the Applicable Federal Rate for loans. Though this really isn't an issue with banks as they are not charities and tend to want to make money.
Ironically, a wealth tax of 1% is equivalent to 20% of the risk free earnings on that wealth.
> Wealth accumulates with no input once established.
This is incorrect, historically you'll pay a ~2%-3% loss via inflation if you keep your money in cash. If you invest (making it capital) in bonds or securities then you will see accumulation, but thats actually a risk premium.

This is true, its typically called "Buy, Borrow, Die" but the reality is that it is only available to a very small percent of wealthy individuals and exists because of the way inheritance is handled ("stepped-up basis"). Even reasonably (not fabulously) wealthy people will still pay retail rates on the loans making the tactic basically ineffective. Last I heard you needed something like 100M+ liquid for lenders to even consider it (presumably, because they will make more off of some other deal with you)
