Your governor believes many (if not most) Federal assistance programs are unconstitutional. He believes in drug testing for the unemployed.
I could be completely wrong, tax stuff confuse the hell out of me...
That's pretty much the definition of regressive when it comes to taxes - people making more are being taxed less, proportionally.
Formerly 15% + 0% (if you lived in WA) capital gains one year is now 20% + 3.8% + 14.3% (if you moved to California in 2013). That's a pretty big difference for the same gain.
Of 43 states with individual income taxes, 7 have flat individual income taxes. [1]
That certainly seems like an argument that could be made, but I don't see that ownership of real property alone is a better proxy for "standard of living" than income is, so I don't see how any such argument would be relevant to the claim made with regard to property taxes. (Consumption -- as is the focus of sales and use taxes -- is probably a better proxy for "standard of living" than real estate ownership is and might be better than income, but I still don't think flat consumption taxes are more progressive against standard of living than progressive income taxes are.)
