Skilled people in the trades can always network with their fellow pros in other trades [you typically work with the others in housing construction, for example], and swap work that you need done, if you can't do it yourself.
We definitely need more tradespeople. I was a machinist for over 40 years. One can make a decent living and be productive, unlike some of the college educated idiots out there now.
Notice I said “some”- like the Marxist trained types and their so-called “professors”…
