The thing is, in isolation, balancing the budget looks pretty easy. It's only because you have to deal with particular interest groups and a populace who has come to believe that any tax increase means they're getting shafted. I was able to balance that budget with the following changes:
1. Top one percent effective tax rate goes from 24 to 30 percent.
2. Higher income goes from 12.26 to 14.26.
3. Upper middle income goes from 7.7 to 8.7.
4. Middle income goes from 4.8 to 5.8.
5. Lower middle income goes from .1 to 1.1
6. Lower income goes from -4.1 to -3.1
7. Social payroll taxable maximum goes to 90% of taxable income.
Those changes alone, with absolutely no spending changes, balance the budget. Now, I'm not proposing that those changes are politically viable, and you can certainly fiddle with my distribution if you think something else would be fairer (I think it's fair because the rich have done much better than everyone else over the past 40 years so I think they can afford to pay more, but I also think that everyone should have to contribute something more or else you get the current problematic belief that the issue can be solved just by taxing somebody else), but I would strongly disagree if you wanted to argue that those changes would result in any substantial change in standard of living for anyone.
I think, numerically, the problem can pretty easily be solved just by taxation alone (though I think it would make sense to add some spending cuts), just not politically.
