as long as you don't live near major airports, (annoys the hell out of me), the industry is looking for ways (except for the obvious, opening a school in a top 10 largest population city in the USA) to recruit and retain more new hires amid climbing air travel demand

 If you live near Tulsa Oklahoma, or Broomfield Colorado, and want to be a pilot or aircraft maintenance technician

So, why hasn't that Spartan College opened a school brank in Los Angeles? San Jose? San Diego? New York? Atlanta? Cities with LARGE populations? Houston? Chicago? 

It's like they are avoiding putting a school where actually large populations exist, with a larger likelihood of a steady supply of students

After all, it's likely that the low pay, grunt work, lousy hours, (to support a multi billion dollar profitable industry) are going to motivate a number of those mechanics to find something less arduous, that pays better. So, the studies that show that the industry will need more than 700,000 new technicians to meet global demand over the next 20 years, from Boeing, and a 2022 report from consulting firm Oliver Wyman looked into the issue, predicting a roughly 25% shortfall in North America by 2027.

Lionel Taylor, a recently retired aircraft maintenance technician from California who worked for American Airlines for more than 30 years, said he seems to still be in demand for technician jobs. “When I go through my email, I see that I'm being offered positions from companies all across America, and I haven't filled out a resume in a long time,” he said.

By the way, Air Traffic Controller pay is only about 22 an hour to start. It's 22 an hour working at a In and Out burgers, here in San Diego. Yes, really  https://www.usajobs.gov/job/818403800  https://www.in-n-out.com/employment/restaurant/home

AT-2152 AG - this is the position level for selectees who are NOT former FAA 2152 Certified Professional Controllers (CPC); salary $40,649 (20 an hour) which is only minimum wage here in California for fast food https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202320240AB1228

So, does the government, or the FAA, or the airline industry feel air traffic controllers worth being paid more? Nope.
