What do you say about a dispatcher who goes to night school for 3 months spends less than half of what an A&P does for tuition, and only a fraction of the FAA required 1900 hrs of instruction - yet makes even more than an A&P? Obtaining dispatch qualification where i went to school was an elective. All that for a job that could pretty much be done with a cell phone app. As long as we are on topic of comparing jobs and pay vs education, nothing against pilots - my college roommate was one, but aside from the ratings and flight time, there isn't a degree requirement. Sure, it would be preferred, but not necessary.
Then for the fresh A&P school graduate, there are 3 FAA tests that must be passed, two written, and one practical with a DME. These are not free. Next step would be gaining experience to put on a resume', unless the budding A&P had some prior experience from the military for example. Most large airlines require 5 years heavy jet experience to qualify for an A&P position. Then if the applicant is successful, and gets hired - they can look forward to working night shift for many years, working on holidays, and having oddball days off. Last but not least, the applicant better be able to pass a drug and alcohol screening. Doug Parker couldn't even pass that.
There is a lot more to it, than you're suggesting with your post.
