I have no idea about CEO compensation in general, but I'm curious what would be a reasonable salary/compensation for someone who manages several large facilities and thousands of staff, some of whom make 7 figures for their expertise. $6M plus perks doesn't seem that high to me, but maybe I'm desensitized by seeing so many other executives make gobs of money.
