My best friend is a plumber and has been working at the local casino now for about 10-12 years, essentially since the day he graduated highschool, minus a year or two of being laid off and working for the contractors. He makes more than I do with my college degree, has decent investments, he got a house something like 5 years ago and is doing pretty well paying that down plus being single and having a room-mate helping out, he’s basically set.
Yeah, you’ll have to deal with literal shit sometimes, (and at the casino apparently you get the seemingly suicidal drunks complaining the toilet is broken because it’s overflowing with god-knows-what.) but the trade-off is most of the time its just working some pipes and pulling out whatever is clogging the works or leaking.
And it’s not like you’re a custodian who has to do the basic routine cleaning and maintenance either; usually things are mostly cleaned up.
Do I want to be a plumber? Fuck naw. But I’ve seen first-hand that it ain’t too bad and will support a good lifestyle.
