One could always try to work for a plumber to learn the trade. Many tasks done by a plumber are unpleasant, but don't require years of training. Maybe they'd accept someone to help them doing the easy or dirty tasks (that they can still bill the customer for) so they can only work on the clean or hard parts, like welding pipes, making threads and waterproofing fittings.
Anyone who can watch YouTube for a few hours a week can learn to change valves, connect a faucet or sink. Declogging sinks and toilets is even easier, and there's still customers who will pay someone else to do it.
YouTube is today's community college. Declogging toilets, installing SAT tv, repairing fans in a computer or changing oil on the car. Everyone has at least some aptitude in something and with some time can learn at least enough to be a slight help for an established small business or craftsman. But yeah, you can keep using it to watch cat videos all day and claim The Man is keeping you down.
