All the flat rate monkeys working on consumer vehicles are working to slap things together as fast as possible (without doing such a terrible job that it comes back) so they can log the book hours and move on to the next job (presuming the shop is busy enough for there to perpetually be a next job).

I take it you work in a relatively high margin part of the industry. The skilled trades is just as much of a rat race in the low margin shops where the vast majority of people start their careers.
