The idea of renting your life to someone else for sustenance is at an anthropological level odd, don't you think?
Also from a capital point of view. Why work harder? In fact why not work easier if you are paid by clock hours.
Return to who - your employer or 'the market'? If your employer fails to monetize the widget you've just made, are you happy to get $0?
It's easier to move risk onto labour if they labour has more direct control over the return, which is why sales people are more comfortable with direct commissions than engineers.
Because my consulting practice is based on operational improvements and not ownership of the end result, I don't work on a commission basis but on value-based pricing.
Anyway, I was also a stoned teenager in food service when I got a job at a pizza shop delivering pies. No hourly pay, just $20 a day plus a $2/$5/$10 delivery fee depending on how far you were from the shop. I kept all the tips and payday was 11:30 or so every night. I've never worked harder or felt better about work than I did coming home with my pockets full of money at the end of the day - it was clear that my showing up and busting my ass made me my paycheck. Ironically, this is called "getting paid under the table" and it's illegal.
