A sole proprietor landscaper making $45-50K a year in California is paying $675 a year in annual registration fees just to keep his newish pickup truck on the road. Why newish? Because the people he's servicing trust a guy with a nicer work vehicle than a beaten down 30 year old Tacoma.
A $900k developer with the same pickup is also paying $675 a year.
Extrapolate this seemingly trivial example across literally EVERYTHING in life.
I'm not saying the highly-paid developer is hurting, but the better question is why does it cost $675/year to register a vehicle in CA? Our income tax system is already highly progressive, so why do we have all these other stealth taxes that hurt low incomes the most.
