50 years ago, Investment bankers had to walk into the Church at the end of the week, and if the pastor/community found out that they had been involved in insider trading, their social lives were over.( Social pressure was a powerful motivator when social groups were near-mandatory religious affiliations.)

Similarly, presidents, senators, and other political figures used to need to attend church every week, and they would have been subject to extreme social pressure if it was clear that they were uninterested in the public welfare.
