It it a total scam and one that keeps being driven home to people.

Plumbers and Electricians and other tradespeople are way richer than most college graduates

and going to get richer as less people enter the field. Society is promoting college and knowledge based work yet overlooking the things that make it run.

Yeah! Can't really do anything without tradespeople.

No hard to have things fixed without them. Took me 4 days to get my car fixed. The dealership had 4 mechanics, the guy said they need 15.

Holy Cow! That's nuts. Hard to find people who want to work that hard anymore as well.
