The market decides value. If a job requires a certain amount of skill, the market sets the wage on that skill.
An engineering firm offering minimum wage would never be able to hire engineers. A construction company, even a non union one, offering minimum wage for carpentry, electrical, or plumbing work would not have any workers capable of doing the job.
And as for your last point, by that logic we should set the minimum wage to $50 an hour, oh wait, then a cup of coffee would cost $35 each.
Your logic requires that inflation and the cost of production does not exist.
The market decides value. What are you talking about? Where is this metric of yours revered by economists exactly?
Yes skilled people do get paid more and they should, but that hardly says much about the economy in general. Engineers and construction workers are paid well in part because of how profitable those businesses are.
If, due to inflation, people can't make a comfortable living under 15/h, that is what matters. 10s of millions of people make less than that. The average fast food worker is 29. People can't afford to go to school to learn new skills. That keeps them where they are. Skilled workers are becoming less and less prevalent in today's economy. To suggest laziness is the main reason for this is profound ignorance. What about all these children in families of working parents who lack proper nutrition and healthcare? Where's their choice in having a better life? If people are willing to work full time, shouldn't they be given a wage they can provide with?
You people are so dense. No one is suggesting we raise the wage to $50 an hour. You people reason like children over this issue. Obviously it shouldn't be higher than 15/h.
