I’d propose the each natural person gets to exempt one property from all property taxes. Corporate persons would get no property-tax exemptions. Then reassess property value and tax each year.
I’d also tax all increases of wealth at the same rate. Wages, interest, capital gains, rents, inheritance, everything. With a large annual exemption for natural persons (none for corporate persons), about the same size as the median income (say $100,000). If a person’s wealth went up more than $100k during a year, that person is paying 40% or whatever on the increase above it.
Taxes have to ultimately be based on the ability to pay. Natural persons have to be able to live with dignity. Corporate persons only get to exist to the extent that they benefit society.
