Thats demonstrably false. People get paid just enough not quit right now and they dont demand a raise because someone else will gladly take their job.
Demonstrate it. I believe people will not pursue a career that requires training and technical expertise if they earn just a little more than MW. Why would they put time and effort into training courses, passing a licensing exam, and annual continuing education, for one example, to earn $11/hour when they can earn $10/hour with no experience or training doing a less demanding job?
Convince me.
That doesnt make sense. I dont know any position that requires licensing and continuing education that only makes $10/hr. If such a position did exist they would do it simply because it brought them some satisfaction with or without MW being raised.
Pharmacy technicians can expect to be paid anywhere from $9-$12/hr in most retail pharmacies, and to be a pharmacy tech, you must first show that you have gone through an approved training course and pass an exam. Then, to maintain your certification, you must regularly earn continuing education credits. You can earn higher pay if you get into a long term care (non retail) pharmacy or if you get specialized certifications. My wife did all of those in her career, so I have close knowledge of the industry. She also taught pharmacy tech classes at a career college. Without those extra efforts, she would have been stuck at a much lower pay rate.
At least one of the students she taught faced just that situation. He spent a lot of money (and time) to get his education, then took and passed the exam, only to find his best paying offer was around $11-$12/hr. Do you really think he would have bothered with all that if he could have swept floors for $10/hr and maybe worked up from there?
