Why is that insane? A CEO is just a job and how much you get paid depends on how much the industry is willing to pay you. So turning down 10mil to earn 3mil is indeed a sacrifice. Unless you have something against people making a lot of money or think once you hit some number you should not say anything bad about the pay. People don't get salaries because they earned or deserved them, they get them because that's what others are willing to pay for their work.
