Do you have more sources on this? I've been looking for good data on the competitiveness of traditional blue-collar "trade" jobs/industry since it started becoming the go-to panacea to all our job woes a few years ago. It seems like plumbing, electrician work, HVAC, etc. would be pretty easily saturated areas; how many plumbing jobs can be sustained per neighborhood, for example?
