Every person I knew working a low-skill job that wasn't a student was working 2 or more jobs to make ends meet, and at least 60 hours a week. Not entirely sure when you expect them to "gain a skill" when they can't exactly stop working since they don't get paid enough to do so. They don't sound lazy to me, they sound exploited!
How do you fix that without changing the system? Should they leave their families to starve? Should they stop paying rent and live in the wilderness? Should they work an additional job? Should they take out a loan they can't afford to pay for the training programs they don't have time for?
There has never been easier, faster and cheaper access to information and learning material in the entire history of humanity. But yeah, if someone loves being the victim and has no motivation to improve their life then that's on them.
The same clowns who couldn't shut the fuck up long enough in high school to learn some ABCs or 123s are now the adult clowns that want to act like their skill-free job is worth $30/hr. Fuck off.
It's always, always, always one excuse after another with these people. They put themselves in a shit situation after countless people along the way have tried to tell them otherwise or steer them toward a better life, but god forbid they listen to anyone. Their dumb asses supposed knew better. Ugh. Clowns.
