Their are downsides to investment banks being private partnerships. On the other hand, I've talked with execs that wish the banks hadn't gone public. Yet they had strong incentives to go public.
Yet they expect to hire good lawyers / engineers / team managers / janitors etc without such golden parachutes.
Why is the CEO position rewarded so greatly? Because the board comprises CEOs of other organisations.
They are the nobility of our era and look out for one another.
I guess nearly every US President and global leader, along with 80% of global CEOs aren't "good" either, because bad things happened on their watch. Some much, much worse than a data breach.
I'm not saying this guy was good, but that your standard is impossible to reach.
Things happening isn't necessarily an indicator that the person is bad, but how they deal with it (in this case, he didn't for many months!) is an indicator. That's not an impossible standard to reach.
Something tells me this guy had no problem collecting performance related bonuses.
