The only two Known Knowns in Life. Well, except for cryogenics believers like Alber (wherever the hell he is...) :

Joking aside, now that we've got both (R) and (D) taking our FUBAR tax code to the forefront, we're gonna have a national debate about

1) the purpose of taxation
2) the definition of tax "fairness"
3) taxation by representation
4) elected representatives relying on lobbyist or super-PAC money

Okay, #4 might be making the argument more complicated, at this time. But still....

By now, everyone's heard that Romney paid less than 15% on his multi-million dollar income, because he had no earned income from salary or wages. It's the same inequitable argument Warren Buffet makes; that he pays less income taxes than his secretary....and that we tax labor and work at higher rates than financial speculation investments. Even our 'high' corporate tax rate has been exposed as a myth, since the mega-international corporation GE paid zero federal tax, and instead received tax rebates.

Can we re-work a tax code that acknowledges the purpose and legitimacy of taxes?
Can we figure out what "fairness" means?
Can we rely on our elected representatives?
