Why Obama has no plan for the debt crisis?

What doesn't Obama come up with a plan to fix the debt crisis? Roger Simon:

Well, the reason for the latter is simple: because he can’t. The minute the president evinces a budget plan, the game is up. No liberal budget will stand up to scrutiny. There is no money left for deficit spending in our aging society. The welfare state is kaput. It’s gone — probably for generations to come.
Of course, there’s always that canard about taxing the rich. That will save things. But the truth is even if you tax the rich at 100%, it barely sets back our entitlement crisis a year or two, while virtually bankrupting the few job creators who remain.
So no wonder Obama doesn’t have a plan. What would it be?
