I understand exactly what regressive means. Percentage of income is not a valid measurement in determining what each person pays for the exact same government, imho. It’s a liberal feel-good equation used to justify charging some individuals a far greater actual amount for the same product. If anything, charge everyone who wants a say in spending (a vote) a minimal tax, and have most government services funded by user fees. If you have kids in public school, you pay a user fee for that service, for example.
