The NY Times has an interactive budget puzzle. You choose the budget cutting and revenue generating options, and it tracks it on a graph.
Of course, it depends on the assumptions used to come up with amount of money that will be cut or generated for each of the options.
A few seem a bit off to me, so they might have different assumptions.
The social security cut is problematic–because there is enough money in the trust fund for more than 30 years, so making any cuts really does not help with the deficit in the near term.
And the amount of money that would come into the treasury if the mortgage deduction was eleminated seems on the low side.
But it’s kind of fun!
