How can Congress possibly balance the federal budget without raising taxes?
It's easy. Make Congress make up for any shortfall in the budget. Take it out of their pay. Cut Congressional pay (House and Senate) for every dollar the budget is in deficit.
What about the president? Well, if he vetoed the deficit budget, he's off the hook. If he signed it, he's liable. Dock his pay, too.
Now, what happens if the deficit is more than the pay of Congress? As is the current situation? Congress is on the hook for the balance. Personally. If Congressman A has twice wealth as Congressman B, he's responsible for twice as much of the deficit.
When that still doesn't cover the deficit, spread the debt around to other members of the government, exempting military pay only.
If Congress tries to get around it by raising taxes, count every tax increase as deficit money, and cut Congressional pay accordingly.
I learned a long time ago, that if someone had the solution to a problem, but had no interest in solving the problem, it was because it didn't personally affect them; it wasn't their problem.
Make it their problem.
