Re: I'm assuming that the USA is where the game is rigged.
It's the American mentality to want a "deal". So, instead of a logical system based on income and family size we have deductions. Not everyone can use them but hey... we have a "good deal on taxes". Around tax time, the conversations talk about how much they got as a "refund" and not grumbling about how much they actually paid.
And let's not forget that the government likes it because most folks miss out a lot of deductions so end up paying more tax than they should.
