This is not at all true; our standards are extremely low for moral behaviour from public figures, and they traditionally face minor or no consequences for even severely unethical or actively criminal behaviour.
You can't say we need to preach forgiveness rather than consequences when no consequences are happening at all; it reads as insincere, and is at best inaccurate.
If you want a specific example though, Nixon resigned.
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.
This world view is not only more accurate, but also more forgiving, and and overall leads to a less angry world view.
