The thing you learn as you get more involved in a company is that the workers on the bottom are paid the highest percentage of the value they create. i.e. bottom tier workers have the lowest margins of all workers, they are already keeping almost everything they create.
So to "balance" this the only way to do it is to take from higher paid workers who already are getting paid much less than the value they create.
That's why these systems are so rare and why they frequently collapse. People _really_ don't like carrying others weight any more than they have to.
