Coke, you mention this in your post, but it bears special emphasis.

A substantial portion the trillion dollar stimulus passed in '09 was for infrastructure. Now, after you've spend that couple of hundred billion on roads, bridges, and the such, what the hell are you gonna do with the another $50B more Obama is proposing to sink into it? After you've already spent that much, how can there possibly be more roads or bridges that need to be built?

And, Coke answered that question. The money must not have really gone to infrastructure like it was supposed to. It was squandered.

So, what are we supposed to expect is going to happen with the next $50B?
