Don't forget personal property taxes. In CA, you not only pay a Sales Tax when you purchase a vehicle, but a tax every year you own it that is based on the value of the vehicle. High value, high tax every year. Also high insurance cost -- and the insurance bill contains taxes.
Also don't forget that wealthier people tend to purchase high-end products. High-end products were more profitable for the producer, and therefor the producer paid more income tax. That income tax got embedded into the purchase price. Lower-profit items contain lower-embedded taxes.
It goes on and on. The more you look at taxes at every level of government, you realize how skewed they are in true Marxist fashion to place the burden of society on those "who can afford it".
Even the "regressive" cry about SS taxes is false since the eventual benefits paid out show those contributions were a horrible investment for poeple at the top end and a good investment at the low end.
Yup!
