While there is a lot of general cleanup work to do in some places, there probably isn't enough manual labor to go around. There are machines that grade and pave roads with amazing efficiency. A new WPA would probably have a large training element since health care, assisting teachers, etc. are the areas that need the most headcount.

Plus this could get us over the downside of shrinking the surveillance state, prison industrial complex, Homeland "Security," etc. If there is a fallback program that always has jobs on offer, the need to create jobs more expensively declines.

Even during the original WPA, I suspect that a lot of the labor was borderline make work. AKA building a stone bridge for a hiking trail in a national park wasn't the most efficient way to cross a stream even back then.
