I have brought this up here before and got all kinds of justifications : he has a big house, he has a special needs kid.
I don't think there is any teacher in NL taking summer jobs to make ends meet.
Breaking Bad isn’t supposed to be a documentary. Teachers don’t have summer jobs at car washes. Tutoring is both easier and pays better, as does summer school. Working at a car wash is an example of shitty choices, as is his entire relationship with his wife. It’s like his decision to go into drugs in the first place. He’s a public sector employee. He does not need to make drugs to get excellent health care. He does it because he wants to. Working at the car wash is not something he needs to do, it’s a way of expressing his martyr complex.
To view temp/gig work with a full-time lens is disingenuous, imo.
