Yes, I am aware that is currently doesn't work that way, hence the mess we have created with the current tax system. I think we need to simplify the tax code to a flat tax for all regardless of age, income, number of children etc.. Everyone uses the services provided. Everyone needs to contribute their share, which I believe should be a flat percentage (we'll say 10%) of their income without any exceptions. We could then eliminate, or at least drastically reduce the size, of the IRS and save bunches of money. Everyone would then have skin in the game and this give me attitude of having the government give all sorts of goodies might decrease too when they realize they are paying for those goodies and the percentages might need to increase to fund expected/desired new goodies.
Also a $90,000 income is a healthy income and should be required to be taxed under the current system.
