What good is a ten year budget forcast?

I notice the Obamanauts have suddenly started talking about the ten year budget, and crowing about the wonderful deficit reductions to come ten years from now. Does any one really believe that predictions for ten years from now mean anything? Or is the ten year talk merely a way to obscure how bad the numbers for this year are? Like predicting the budget deficit in ten years will be less than next year and claiming that is a "reduction".
Honesty requires us to talk about this year's budget, not the imaginary future budget.
