Witness this awesome graf in Ezra Klein's latest Wonkbook:
This is a bad time to do a half-measure on infrastructure. We have literally trillions of dollars in unmet infrastructure needs. We have massive unemployment in the construction sector. Materials are unusually cheap because of a depressed global economy. Borrowing is unusually cheap because we're one of the few safe havens left in the global financial market. And it's cheaper to repaid an aging bridge today than rebuild a crumbled one 10 years from now. So waiting to do the bulk of our infrastructure passing a half-measure on infrastructure investment later is like waiting till after the big sale ends to buy your groceries. It's just bad financial planning.Things are not working on the most fundamental level.
