Back in the 80s I worked for an insurance company for a year. The bread and butter of the outfit was an army of door to door salesmen who busted their chops out in the hinterlands convincing John Q Public to buy their policies. I worked in the personnel dept. in the corporate headquarters a few blocks from the beach in Santa Monica. I was privy to the salaries of everybody in the company. The salesmen were strictly on commission - 40/60 split with the company. The office staff was paid close to minimum wage and were treated like slaves. The managers, however, who basically sat around on their asses and planned vacations, all made 6 figures and were awarded with generous quarterly bonuses. However, the two guys at the top lived better than most movie stars. Private jets, helicopters to transport them from office to home, salaries of 50K a month each plus multi-million dollar bonuses. It was an eye opener. The following year I went back to teaching. Crappy pay but no arrogant asshole bigshots.
