This is disingenuous: the fundamental principle of socialism and Communism is democracy. And, credit where credit is due, capitalism forced us to socialize the production of goods and services (it now takes many people to "produce" anything). Currently, there is no discussion about who gets the profit of socialized labour, it goes to the people who own the workplace, which are rarely the workers.

So, to make your example realistic, you and this other person are part of a community that grows apples (pick any rural community). Together, you all own the fields.

How do you decide what each person gets? You come to a consensus. There are so many variables; is the other person injured?young?sick?old? Or really bad at picking apples? Maybe you are on some apple picking super serum. How do you decide who gets what? The same way people usually do; you decide together.

In your example, having a blanket rule as you suggest would never work, and would be unfair, but it is what happens now in our advanced capitalistic economies. If you pick 1000 apples for a company, how many do you keep? Or more realistically; once the apples are sold, how much of the.profits go to you? You have no choice. You work, get paid, and go home. You work harder and you end up with just about the same amount at the end. The only saving grace is if you work hard enough, one day you might be promoted by the generous owner to a position where you are no longer the poor schmuck who does all the work. But that poor schmuck will always still exist, it's just no longer you.
