Literally nobody would be left.
If every C-level in the world is morally suspect, we have a bigger problem. Seriously, is your claim that being a bit iffy is a pre-requisite for the job? That's a pretty damning statement about capitalism if that's the claim.
In my experience it is much more accurate to not see the world in terms of good and bad people, but to accept that each of us have the capacity for good and bad in ourselves. To quote Solzhenitsyn: the line between good and bad goes through the heart of every person.
This world view is not only more accurate, but also more forgiving, and and overall leads to a less angry world view.
