I do agree with that. The value of labor does exist but it can't exist without the demand for certain types of labor in the free market. Karl Marx wasn't the only one to believe in the theory of value of labor, Adam Smith too, the father of free market capitalism. I was never into sports and even find them overrated but since they entertain a lot of people and are very popular and draw in a large crowd, I have no problem with sports stadiums and teams drawing in the profit it draws in and the players such as Michael Jordan, LeBron James, etc. getting paid the large amount they get paid, that's not a problem to me, they are getting paid a large amount they did earn fair and square. They do have a lot more money than me but why should I be pissed off at them? They work in a job that requires the skills they have, a job they have the skills for, a job I don't have the skills for and never cared about persuing as a career and never intended to gain the skills for. They have nothing to do with me. They work in their own field that I never wanted to work in but they decided to work in, they aren't people I did work for and didn't pay me, so it's none of my business of what they do in their job and how much they get paid and I have no reason to complain about not being paid $1000 an hour for doing a menial fast food job. I am just saying that those who do whatever work they do need to be properly compensated for their work and the service they provide and those who they work for do need to pay as promised and not screw them in the deal and not try to act like they are entitled to people's labor for free, be it a highly paid sports player or a minimum wage janitor, both types of workers need to at least always be paid what was agreed upon in the first place.
