Taxation is not necessarily regressive. Where I live, income tax accounts for almost all of the tax I pay, and income tax is very much progressive.
But also where I live, the garbage man is not a public employee, but an employee of a private garbage company. So my taxes don't need to change, instead my garbage bill goes up. That would be regressive, since a garbage bill is a higher percentage of poor people's income. But some poor people just don't pay the garbage man, and instead take their garbage to the landfill themselves, which is way way cheaper.
Incidentally, you can make the same argument about minimum wage increases - the cost of getting low wage work done increases, so prices increase. I don't want to get into an argument about the effectiveness of that, but the evidence generally suggests minimum wage works better than conservative naysayers sometimes claim.
