LOL flu, the challenge for Hoover Dam isn’t capabilities (although at this point, capabilities are probably a problem too, particularly in many manufacturing segments), it’s all the other stuff from changed expectations, to worker rights, environmental restrictions, etc.
I’d make a joke about the Jungle and Chicago, but I’m not sure the pork operations today in North Carolina with their steady stream of recruited labor from newspaper ads in foreign countries with a wink and nod from governments are any better.

Sending jobs overseas started out about being cheap. Then it became about skill, because surprise, when you stop doing something, you stop being good at it.
