I thought street crime was a pretty terrible business for most? https://www.youtube.com/watch?v=5UGC2nLnaes

Also, bank robbery isn't usually very lucrative, and they've made it harder and less lucrative over time. "According to the FBI a bank robbery averaged a take of $4,000 in 2009, which may not have been sufficient to yield the thieves a positive return on their enterprise. You see, at today's prices, the robbers would need to expend $4,442 for the guns, bullets, and masks used in a typical bank robbery." http://bastiat.mises.org/2014/09/the-basic-economics-of-bank...

Some crime has been made pretty unprofitable.
