I was a mechanic in the Army, worked in the trade for years after. Now work as a pilot. It is a fine trade with a lot of good people in it. I still run into guys I worked with over 2 decades ago who are still employed and happy with it, many making into six figures.
Kevbo sounds like someone full of sour grapes.
Those who work at the large overhaul facilities have a job similar to factory work, doing tasks from work cards which can be tedious. Others work on live aircraft between flights which requires troubleshooting and a fix or MEL. I also spent some time as a mechanic who flew on the aircraft (they were old) in order to take care of anything that may come up.
Mechanics are not a different class of people than pilots, they just do a different job. Many worked carss. motorcycles or other equipment growing up and have a knack and love of working with their hands.
