You make an excellent and fair point if it stops at this. The problem starts when the successful business starts to take advantage of loopholes with their wealth(lobbying, offshoring income, jobs) to advance their ability to make profit at the expense of the labor that doesn't have this ability. So although the pact seems equitable in the beginning- it breaks down one side take unfair advantage of their position. German labor is an example of where the workers have managed to gain from the productivity of the companies mostly through organized labor but also because the companies realize its better to share the wealth. Hence- I'm only guessing we don't see super-rich German billionaires.
