There is a huge demand for low-skill labor in other industries. Stuff like plumbing, HVAC, and a ton of other traditionally unsexy jobs that can barely keep enough people in a town to perform these jobs at higher costs than normal.
Those jobs don't often pay well until you graduate out of journeyman / apprentice, or are a business owner. They usually require some training and testing ahead of time. They also carry a higher risk of serious injury or death.
I wouldn’t call plumbing and other trades low skill.
