can you define public infrastructure?

If you mean putting more political appointees on the payroll, I can see where that is a failed stimulus.

Here is New York we have a number of state parks with infrastructure built by the CCC... civilian conservation corps.... that are now in need of repair...

that's what I call public infrastructure and I think we got plenty of return on that investment.   And putting in money to get another 80 years of public benefit in addition to putting folks to work... how is that a failure?

To bring this a little more relevant to folk music... it was New Deal money that financed John & Alan Lomax during their recording efforts in the later 1930's. Another good investment in my opinion.
