It's because that's the intersection of value that an employer is willing to pay for and people are willing to work for. If everyone was paid exactly the same, then there probably wouldn't be any doctors because they'd never break even on their medical school payments, etc. Higher wages is society/capitalism's way of incentivizing more people to go into that area. there's greater need there. By paying more, more people are willing to join that occupation. It seems weird to take the fruits of someone's labor. I mean, if you can make your bed twice as fast as I can, I don't demand that you come over and make 1/3 of my bed. And if you grow your crops, but do it much better, yielding more fruit, it would be wrong of me to take a 1/3 of your crops.
