In performance-based commission driven environments there's always a built-in incentive and a compensation plan to perform and produce. I know tons of people that didn't go to college and make way more money than people that did go to college. Thoughts about incentive-based compensation? Seems like people crush themselves doing brutal hourly jobs and have nothing to show for it or others get into roles that help them at least in part determine their own paycheck to a degree and don't work nearly as hard.
For example, if you're reading this on a smartphone chances are the person that sold it to you made a commission.
