What difference does that make? Why does a heart surgeon make more than a burger flipper at McYuck? Could it be because of the skill and training required to reach those positions?
There's a reason unskilled labor makes unskilled wages. I don't think college is the only path to a lucrative career, the trades are increasingly on par with people with degrees, alot of that has to do simply with supply and demand. A good tradesman makes $100,000/yr currently but like everything else they dont start there, it is after years in the feild and experience.
Anyone can flip a burger correctly with about 2 weeks of training, you need less training than that to pick up golf balls. To wire a house correctly so it doesnt burn down takes a little longer, to tinker with someones heart so they dont die on the table takes even longer.
A person should get paid requisate to what they offer to society, knowing how to put extra ketchup on a burger doesn't rate that and shouldn't.
