It's disconnected alright. There's only 3 companies advertising for jobs on his careers page. And one of them is a franchising company (Mr. Sparky). Trades are very competitive. Just look up the number of electricians in your area. It's a race to the bottom in the trades.
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?
