What is a living wage? That depends on what the cost of living is.
Ok, so define that today. Be specific. What should the complete and total compensation package be for the least common denominator position like a burger flipper.
As the cost of living goes up, the cost of a living wage goes up. Since prices on things rarely drop, that is a number that will continue to go up over time.
Especially if you artificially increase wages.
And you say that flipping burgers is “unskilled” labor, a designation I already balk at because “skill” is itself a nebulous concept
You can balk at the designation all you want but it doesn't change the fact that the less skill a job requires the less the labor is worth. Almost anyone can be told "flip the burger before it burns" or "sweep the floor if it is dirty". One does not even need to be able to read for these positions. Not everyone can be told "build that airplane" or "cure that disease" or "run that trillion dollar company".
If I grab 100 random people from the population I would venture to say that 99 of them are qualified to flip burgers. If there are 7 burger flipper positions open one probably doesn't have to pay much, this has nothing to do with greed, its simple supply and demand math. I would also venture to say that perhaps 5 of the 100 people might qualify for an engineering position. If there are 7 engineering positions open one will probably pay through the nose for an engineer. This is a very simple concept.
And most people who do “skilled” labor will not accept “unskilled” labor jobs, even if they are offered to them with good pay
Your damn right! Why would you even suggest that a Doctor would want or accept a position flipping burgers versus being a Doctor? Even if the compensation were identical why would you ever even suggest wasting that education, skill and knowledge? Don't care for the Doctor analogy? How about a seasoned wood worker, a craftsman... why would that person ever want to flip burgers for the same compensation?
So many people act like they are entitled to the goods and services produced by “unskilled” laborers and that if they are in a “skilled” labor position, they are better than workers in “unskilled” positions. It’s sociopathic.
I don't see this at all and I do not feel the "skilled" population feel entitled to anything. I pay for my goods and services, doesn't matter if the goods are a Five Guys burger made by unskilled labor or an engine for car built by someone with years of skilled experience and equipment. I have bought both recently and I didn't treat either person differently, I was very nice to the cashier at Five Guys but there is no way in hell that position is worth $20/hr. This is why cashiers are being replaced by kiosks. Enjoy the $0/hr you earn after being replaced by a kiosk.
