Trade schools have always been an option. My sister's ex-husband went to a trade school to repair airplanes. Nigga pocket stayed swole. Last I heard he owns a nice ass crib in the sticks with a couple of acres. My wife's cousin's husband went to trade school late in life and came out as a boilermaker. Did his apprenticeship, journyman shits, and is now a master boilermaker at 48 (never too late for it). Dude is clearing serious money.
Auto and aviation mechanics are always in demand. Plumbers, CNC operators, dental/medical assistants, all sorts of shit people can get into without going to college and you can come out the other side making decent coin.
