Let all full time jobs pay good enough. Want skilled labor? Better give incentive to take that responsibility, or we will all work high school level jobs.

Having worked in "high end" jobs and "high school labor" - a lot of incentive will already be that you don't break your back. Being able to sit. Being able to take coffee breaks and chats in the kitchen. I'd take my husband's programming job over my jobs as a high end fashion salesperson or a lab technician every time, even if I made more in my jobs than he does.

I think also a lot of people have an innate desire to learn and move forward. Given the opportunity, my guess would be that a lot of people would decide to get further education. Also responsibility. Some people enjoy having a lot of responsibility, lead teams, etc. Imagine if just the people who actually wanted to do this for the sake of it became team leads or managers, not because they wanted to make more money in that position.

At the end of the day, everyone should be paid because they put time of their day doing something they wouldn't do for free. I don't care whether you're a lawyer or making sandwiches. If both have worked 8 hours today, both should go home with a nice wage that they can live off.
