Not just America. I guess most (all?) countries have that problem.
In Germany, Hitler built the whole Autobahn system in a couple of years. Now it takes 8 years to upgrade a 5km stretch of the Autobahn from 2 to 3 lanes.
Yes, Nazi Germany was using lots of slave labor, but these days we have so many machines that it would require much less workforce to achieve the same result. Yet, you often see construction machinery standing idle next to the Autobahn for weeks, if not months, with no work being done
