What matters isn't work, but production to others. If work was what mattered, people would get paid for beating video games since beating video games is hard. Yet unless someone pays you to beat a videogame, your not being productive to others and therefore if you beat a videogame in the vast majority of instances, you do not deserve to get paid for it.
We see something similar in income inequality. Jeff Bezos got rich by being productive to society. Do people that work harder contribute more to society? Generally, however it is not a given. Jeff Bezos contributes to society significantly more than any other Amazon worker by a long shot since the stock and the company he created contributes more to society than an individual worker does.
You could argue that collectively his workers contribute more to society than Jeff Bezos and if your correct, collectively his workers earn more per year than Jeff Bezos. But on an individual level, one Amazon worker contributes significantly less to society than Jeff Bezos does, so they get paid significantly less.
If a worker wishes to contribute more to society in order to earn more money, there are millions of high paying out of highschool jobs they can get. If they get these jobs, they will be more productive to their society and they will earn more as a result.
