There's only so much CEOs on te market with proven track record and obviously companies prefer them over unknowns. Also, for CEOs, even a small difference in skill/experience can translate to huge changes in financial results (via better decisions which affect the whole company) The janitor's situation is exactly the opposite. Virtually anyone can do janitor's job and also skill/experience differences don't translate to company's higher profits. Hence, the pay for janitors sucks. Programmers are somewhere between CEOs and janitors both in term of supply and impact on profit.
