Property taxes are regressive, so I'm not sure how that would help.
You know what really killed the rich? SALT deduction limits in the Trump tax plan. That policy actually caused the rich to pay more in taxes.
That's why CA tried to work around it by trying to classify property taxes as a charitable donation.
Wait and see, the Dems will pass a new sweeping tax plan that won't include the SALT deduction limit and they'll claim that it taxes the rich more.
