The problem is how do we actually implement this? For example you used the word "profit", but what if the best move for the company during a period is to reinvest profits and then contributor x leaves having contributed significantly to growth (but little profits). An idea that I find interesting is that all employees get voting shares which convert to nonvoting when they quit. And for non-employees, only investors at key capital raising offerings get to get voting shares, which also converts to non-voting on sales of the shares.
