Paying a drywall hanger more doesn’t increase wages for a civil engineer.
Are teachers going to be paid more if cooks make more? No.
Are computer programs going to be paid more if hotel maids make more? No.
What actually is going to happen is widespread business closure because they don’t have labor.
If a drywall hanger makes close to what a civil engineer makes, who would waste all that money on college?
I've spoken with drivers in the past that told me college was a huge waste of money. They got their degree, were able to get a job, but truck driving paid better which is why they were truck drivers in the first place.
Back in the 80's I was involved in medical fixing home medical equipment. In the morning we all gathered at the coffee pot, and had various conversations before getting to work. At the time, UPS was on strike. We were opening up a pharmacy in our building; not the kind that serves the public, but to make various medications for our home customers. At the coffee pot, we struck up a conversation about the UPS strike. Our newest employee, the pharmacist stood there listening on. She was a bit shy as she was only with the company a few weeks. During our conversation, she walked away in a rage. We kind of looked at each other like WTF is she mad about?
The coffee gang broke up and as I was leaving, the pharmacist (still very angry) approached me. She had her monthly pharmacy magazine in her hand. She said READ THIS!!! The article was about the UPS strike. In it they claimed the senior drivers at UPS were making 52K a year. A pharmacist on average made around 60K per year. She said "Do you know what I went through to become a pharmacist! Do you know what my parents went through? Had I known this bullshit, I wouldn't be overseeing this pharmacy construction project, I'd be dropping off packages right there (pointing to our overhead door where UPS dropped off).
The industry was hurting for pharmacists for years after that. Today a pharmacist makes twice as much as a pharmacist made back then. You have to make it worth the effort to make such an investment.
