I'm in tech after a decade working blue collar, most of my friends are still working blue collar, and they're all burned out
Blue collar doesn't just pay you poorly -- it's also tedious, and there's a pervasive sense that nobody gives a damn about you, your safety, or really anything about you. "nobody" being managers, but also your white collar coworkers who "work upstairs", customers, security, etc.
You have very little autonomy: you'll tend to have to ask permission to go for a bathroom break, or to step outside for a minute to get a breath of fresh air, or if anything is going to cause you to be more than 5 minutes late for your shift. Yes, you'll have to beg and might not even be allowed to attend funerals of close family members. You may or may not have to help the customer who keeps sexually harassing you. You probably will be asked to speak to customers with a certain tone and facial expression regardless of how awful you're feeling. Nobody cares that you just went through a breakup
RE safety: you'll have employers doing everything from getting you to work with wiring that isn't up to code when you're not an electrician, to lifting things alone that nobody should lift alone, to working at an unsafe pace, to working during small disasters where half the business is underwater. You might not even be a full employee -- you'd be surprised how many dishwashers, waiters and cooks in San Francisco restaurants are employed as independent contractors but are effectively employees
You aren't making much money, so commuting will tend to be a long slog. You might even be working more than one of these jobs.
Yes, I've had "cool" low wage jobs with nice managers that tried to treat me like a human being. I know those exist. They are exceptional and often don't last
Also I am not writing this to single out the parent, just want to affirm that your boring white collar job is better in ways you probably can't fathom and confirm that blue collar jobs are very much prone to burnout
