on Japan, which did what The One wants to do here... and it failed miserably.
Pertinent quotes, for those who don't (or don't want to; the Times wants you to get a free "subscription" to read online articles) read the whole thing:
Japan’s rural areas have been paved over and filled in with roads, dams and other big infrastructure projects, the legacy of trillions of dollars spent to lift the economy from a severe downturn caused by the bursting of a real estate bubble in the late 1980s. During those nearly two decades, Japan accumulated the largest public debt in the developed world — totaling 180 percent of its $5.5 trillion economy — while failing to generate a convincing recovery....
Economists tend to divide into two camps on the question of Japan’s infrastructure spending: those, many of them Americans like Mr. Geithner, who think it did not go far enough; and those, many of them Japanese, who think it was a colossal waste.
Among ordinary Japanese, the spending is widely disparaged for having turned the nation into a public-works-based welfare state and making regional economies dependent on Tokyo for jobs. Much of the blame has fallen on the Liberal Democratic Party, which has long used government spending to grease rural vote-buying machines that help keep the party in power.
That last part certainly sounds familiar.
