The housing shortage has nothing to do with a lack of electrical engineers or plumbers. It’s entirely self inflicted and cheaper electricians will not change that.

More directly: I doubt there will be a meaningful increase in housing in states that have banned construction of new data centers (NY, Maine) than those where data centers are allowed to be built.

There is almost zero overlap between residential and commercial electricians. There is a shortage of residential electricians because the customers are a nightmare to deal with (both builders and homeowners, homeowners are incredibly entitled and I refuse to deal with them, lol) and the pay sucks.
