I think the best comparison is Japan. Huge real-estate bubble fueled boom times, followed by a lot of spending to try and stimulate the economy Keynesian style. If it does not work, you get 20+ years of recession. At least America's population is growing so that might make a difference. Also America's infrastructure is in bad shape, as opposed to Japan which went into its recession with top notch infrastructure. This means infrastructure spending in the US could be more stimulative then it was for Japan.
