Whether the spend-the-way-out plan will work or not, i don't know. But some people obviously believe it will. The intent behind it is for the benefit of the country, he doesn't just want to be frivolous with a load of cash. It's like the healthcare thing - Obama wants public healthcare, why?

Of course!
