Wouldn't that also force the less wealthy to sell their assets to pay the tax? They have less cushion and fewer assets, so they would be more likely to need to sell and reduce the compounding they could achieve, leading to less upward mobility.
But, I'd be curious to hear what do you (and people in general) consider wealthy-but-less-so, if that makes sense. Can we try to assign very rough dollar ranges on these categories?
Probably the simplest way to assign ranges of income is to apply statistics to the unadjusted pretax income in the US. It would probably make sense to adjust it based on COL too. I'm not sure what numbers and adjustments the following distribution used. I did not expect to see 10% of households making over $200k. That seems insanely high to me, but maybe that's an effect of HCOL places like Silicon Valley and dual income families.
