That is what mobsters and pro-mob people always say... but look at all the other corruption, blah blah blah.
That is true, but big banks occasionally get caught by the SEC and go to jail/get punished, too.
So why whine when mobsters get caught and go to jail?
As a logical construct it's nonsensical to say that ubiquitous corruption translates to corruption being acceptable.
It just means that the mob has a lot of company in the sewer.
