It's
* being a mechanic (so you don't have to pay $500 for a $200 job).
* having a job with flexible hours (This happens on the way to McJob and your late? McBye Bye.)
* having someone else dependable with a flexible job (Friday night and everyone know you know is working at McJobs?)
* having someone to take care of your kids so the kid is at home/daycare/babysitters and not freezing in your car
* having spare money so the choice isn't food vs radiator
* being able to easily adjust to different circumstances.
Not everyone can lose a car and adjust with minimal effort. car breaks down and you expect McJob holder to be able to afford another car? thousand(s) for fix? downpayment on a replacment in short order?All of this revolves around the fact that he's in a good place, and able to count his blessings. If all you got out of this is "you gotta be a mechanic" then you need to re-read it.
