Everyone knows the problem. The cure is where the debate is at.
You can call partisanism the problem, but ultimately, it is only the effect that the problem is having.
The problem is overspending.
Apparently most Republicans and most Democrats feel that they can spend a country into wealth using fiat money.
Each side says it will overspend the country's money better. Republicans simply usually say that they'll balance the budget, but instead ignore debt payments and spend more in defense, trying to decrease medical and social programs, the last if they're not completely brainless. Democrats usually increase everything but Defense, leaving it as is.
It's what the US has been doing for 30+ years hard.
The results are predictable. Even Machiavelli said that it was the policy of fools to do such a thing as this.
"Waaaah, we have a ****huge debt that we can't pay! We need to cut spending to get rid of it before everything goes to ****!"
"Buuut I dooon't waaannaaaa! Muh social benefits!"
"But if we keep spending, we'll go bankrupt, and you won't get them anyway!"
"Shut up, you're thinking of the long term!"
GDP?
15.68 trillion USD (2012)
Spending?
Know what I say? I say cut
everything in that pie chart in half or less, except for the interest payments which may double, to perhaps start paying off some principal.
