Many episodes have the same theme

Ponzi scheme or real estate fraud.

A couple of episodes I really liked that weren't on those lines were the ones about the twin sisters selling nuts and bolts who overcharged for shipping and ripped off 20 million dollars from the government and the lawyers who ripped off their clients in Kentucky and ended up in prison.
