You have to remember...
That most CEOs are childish attention-seeking sociopathic narcissists - no-one else would do the job. If they don't have their servile minions fawning over them 24x7, their little egos get bruised and they get all petulant.
So having a CEO lecture us on successful home/work balance is akin to having Jimmy Savile lecturing us on successful child-care and mortuary management.
