The reason this doesn't work is because there is no agreed price for someone's time. If I research for a book for 20 years while I was living on my normal paycheck how much money should I make before relinquishing my copyright? If I paint a breathtaking picture in 5 minutes on a napkin I will abolish my copyrights after selling a copy for 3$?
You pretty much described every corporation in the history of mankind. This is what they always do.
