This. Even if you WANT to get into trades (I have fond memories of woodshop, I'm fascinated by woodworking videos on Youtube, I would love to learn how to build a house), the barriers to entry are just as bad as tech bullshit. You can't just walk onto a job, you have to have credentials. They won't teach you, you can't just tag along and learn, the tool and material cost is way too high to just grab some and learn on your own. I've talked to a few of these guys, and they get salty when they learn I have a fine arts degree (which included several sculpture course, so working material with your hands, measuring, all of that crap), even saltier if I let slip that I'm gay or a progressive or an anime geek. You can't get your dumbshit kids/grandkids involved, I'm the one who showed up, and you're gonna bust my balls over stuff that's completely unrelated to work. Oh, and you want to constantly push me to overwork because you won't talk with your peers and set limits with clients? And, again, these are the guys I could talk to, the VAST majority of the market are people who will literally only hire family or family friends.
There's a massive institutional problem with trades, and shit's gotta change. I'd even put it up to gov't to get involved to get involved. Not just handing money to LLCs, actually building up a corps with good pay and decent hours. Even go so far as to make it a loss leader for a time. There's so much shit that needs to get done and it's clear that private industry isn't equipped to handle it. Flush 'em out.
