Considering CEO pay, assume a CEO earns over $2 million a year, and after 5 years has amassed $10 million in savings. If he earns a 10% return, he would earn $1 million per year indefinitely, enough to live very comfortably. Given this (they don't need more money) what gives them an incentive to put their all into the company?

Please answer in 4-5 paragraphs. Thanks.
