It's a bit depressing that the types of big and important infrastructure projects, things that were commonplace a hundred years ago, seem like impossible dreams. And Krugman's obviously correct that high unemployment will lead some to conclude that Hoover was right.
I know not everyone shares my personal infrastructure priorities, but I don't think it's especially controversial to say that we don't do much thinking big anymore. At least the second trans-Hudson rail tunnel will likely be built, though I'm not so sure about New York's 2nd avenue subway.
