Massachusetts implemented a 4% millionaire tax in 2022 and a small capital gains tax. The results?
- extra $3b in tax revenue, extra $1.3b with the capital gains changed.
- passed a $2.5 billion infrastructure & education bill
- millionaires in Massachusetts actually grew because of the economic expansion
- collective wealth of the people in the state went up by 40% two years after it passed
It's proven that it works. We just need policies that benefit people and not just the rich.
