Here's some food for thought:
* Global financial crises: Banks were paying (bribing) ratings agencies to rate junk bonds AAA.
* Savings & loan crisis: widespread fraud & insider abuse.
* Bernie Madoff: Ran the largest Ponzi scheme ever, with an estimated fraud total of $65B raking in $17.5B in invested cash.
* Enron: straight up accounting fraud sprinkled with intentionally causing brownouts in California to pad their pockets with a side bonus of making Gov Davis unpopular & get him recalled (Enron was closely aligned with the Bush administration).
* Nixon straight up using psy-ops against Democrats & finally trying to burgal the DNC offices.
In terms of stats, the FBI does a few hundred bribery and corruption cases annually. Are they good at catching white collar crime? Well such crimes regularly take more than 5 years to investigate.
And hell, some things that are basically lying and cheating are straight up legal. Usury is legal with minimal to no regulation of payday loans. Pyramid schemes are legal as long as you call it multi-level marketing.
The list goes on and on.
