Economic Stimulus Package

I've seen very little (i.e. no) analysis of the "economic stimulus" package passed by the House, with the encouragement of the White House. It's about $150B. I assume this will all be added to the deficit. So it will cost something over the next X years. It will also presumably create some revenue over the next X years. So how does it all figure out? This, frankly, doesn't sound like a very hard economics problem, one with probably some existing data already. Are we gaining more in revenue than we'll be paying in interest? It's a simple question.

So where is this analysis? Or are we just going to pile this on top of the deficit without regard to its consequences? Can't the grown-ups in charge of our country answer even these simple questions?

Why aren't journalists insisting on this analysis?
