What would happen if all the crime rates drastically went down?????? Like if private citizens decided to start protecting themselves.

A major part of the economy would collapse. There is a reason why the USA has more prisons and more people in them than any other country in the world. BECAUSE CIME AND PEOPLE COMITTING CRIMES is good for the econemy, it create it's own very large econemy, when being a criminal is a good business decision.

How could being a criminal not be a good business decision. The taxpayers pay for the criminal justice system which is in place to protect the criminals from the good people which are the "taxpayers". The criminal justice system allows criminals to operate with some level of protection because the " tax payers" have a false sense of security. The criminal justice system needs to keep the prisons full, the DV, DUI, substance abuse econemy rolling,,,, lots of house, car and cell phone payments need paying. Lots of people need to go to jail to make sure these bills get paid.
