I've said a number of times I'd be absolutely in favor of the following scenario. Give a 1% per bracket increase across the board. Also give a 2% sales tax on all non-medical or food goods. The sales tax money would be tracket in a seperate pot and would ONLY be used for the paying down of our debt. Meanwhile, the budget each year would be adjusted for inflation and then have to be reduced by 5%. If the government spends more than the budget allows for, then the following year the tax bracket increase and sales tax increase expire automatically.
If the government is actually making significant efforts at reducing our spending, and if I know some of the money is going directly to paying down the debt, I'm willing to give up a bit more of my money to the government. However, if they fail to live up to their end, then the tax burden should be removed.
That said, sadly I don't think we'd ever see a trigger system like that actually occur.
