I understand, and appreciate that view.
Now, here is my counterpoint. This isn't the early 1900s. The population is FAR FAR more mobile than previous generations. Already I can move to Puerto Rico and get a 0% tax rate (plus whatever RE tax is). There are a TON of the wealthy and business owners that have been doing this in the past decade. Additionally, while my wife was born in the states, here parents were not. They have discussed moving back to their home country multiple times, and if tax rates go higher, I would consider that.
Case example - Elon already moved out of CA to reduce his tax burden.
The days of even close to 90% marginal tax are done with, never to return. The "rich" are far too mobile, and pushing their rates up too high will just push them out, and then you get nothing, not a penny.
Also, it kinda chaps my ass a bit when I see people on the socioeconomic scale far lower than me milk the system to not pay taxes. Example, had hundreds of thousands done in exterior work for a pool + landscaping on the house we bought 5 years ago. The workers insisted on being paid in cash, they would not accept even checks. I wasn't inclined to report them but anyone that thinks tax-avoidance is a "rich man's" game is not paying attention to the world around them.
