Oh, I'm sorry, is "dumb" too impolite for your delicate disposition? Is naive more acceptable to you?
As for your questions, I'll do you one better. There should be no income tax. The very legality of that mechanism is in question because it isn't supported by any language in the Constitution.
But, we have it none the less. And, that's my point. We live in a world with an entrenched political system that is simply not going to level the playing field because to do so necessarily shifts the power away from those who crave it to the ones, the general public, who are too ignorant to realize they need it.
IMHO, life is too fucking short as it is. Be happy, learn the system and try to carve yourself out a comfortable existence while you're walking around this ball of mud.
Of course, you can also go chase some windmills while you're here and try to fix this mess.
And, finally, you can just sit around and not do anything other than bitch and moan about the way things are ad nauseam.
The fact that any of these choices are equally available to you is, IMHO, the very sort of freedom that this country was founded upon and still exists today.
