>but were filled with loopholes and deductions in that the effective tax rate that was actually paid was much lower.

Yes, thanks for reiterating my main point.

Now if we use that same mindset and apply it to a wealth tax...

Hence my main point. Taxes aren't all about extraction of money, they also help to nudge people to do things they normally wouldn't do. So nudging them to actually help the area they are in is really powerful.

Or they can leave. If so: good. Make room for those who do want to innovate and not extract money from the people (and more beach space).

Not all billionaires are "job creators", especially given the actions taken the last few years. That's why some of the legitimate "millionaire flights" that do happen don't necessarily impact the way that's predicted on paper.
