Actually, yes we can. It worked in the 1920s. it will work now.
Hmm--1920's---

I assume you meant the 1930's? No it didn't work. You can read a book called the Forgotten Man--which will tell you that we got little spurts of employment gains during the 1930's with all the road and bridge work. But as soon as those projects were completed--those jobs were gone--and unemployment rose again. The ONLY thing that brought us out of the great depression was WW2.
Nope. I meant the 1920s. Harding, followed by Coolidge, cut spending and cut taxes and escaped the Depression of 1920 in a very short period of time which was much deeper than the 1929 Depression.
Hoover changed that policy, FDR continued Hoovers policy of government intervention. They had a 12 year depression.
Coincidence? Is it a coincidence that government intervention now is prolonging the recession now?
Absolutely not. History repearts itself.
