technically the tax on your wages is the same as income tax unless we are talking about investment income taxes which is a whole different can of worms, but yes we get the point, shit is way out of hand.

you could add in even more layers like you pay income taxes on your wages, then you invest those wages as retirement into a corp stock, that company turns a profit they are then taxed on that profit, and then you are taxed on the profit after the corporation is, then you are taxes on when you spend it. In this scenario, the government dipped its dirty hands in your income 4 different times.
