A quick search of articles will tell you the CEO pay among the largest health insurance companies is $10-$11 million. Of course, that is not salary but total compensation which includes benefits, stock awards, etc.
The implication is that such pay is a factor in health insurance costs; premiums.
The fact is CEO pay is insignificant in the premium equation. For the largest insurer it comes to less than $14.00 a year per insurance contract.
