I do know 1 thing :
To accomplish a balanced budget, you'll need less unemployment numbers then during the W.Bush years (he couldn't balance one with record low unemployment - and not only that, but all time record deficits at that time), plus the US will need much more growth (exports), and needless to say, the payments on the national debt are much higher now, so they need to find extra money for that, too.
And, not to forget, obamacare or not - ever rising healthcare costs that needs to be covered as well.
And only then, can the budget be balanced, period !
Ofcourse, a nice all around tax increase can change that all. Cuts alone won't cut it !
