New violent crazy people are born every day.

And any system that breeds poverty will always breed crime. Here in the U.S. we lock up more of our own people than any other country on Earth, yet our crime rates are still sky high when compared to anything that's not a Third World hellhole.
Agreed, but I am of the opinion that violent, crazy people are made, not born, and that with the proper incentives, and the removal of our 'criminal colleges', that production rate can be brought WAY down.
I also contend that the removal of taxation and minimum wage would drastically reduce the amount of poverty, as well, further reducing the production rate.
"Very quickly," from an evolutionary standpoint, means 'just a few million years.'
I'm using it more on the scale of 'the antibacterial resistant bacteria developed very quickly'.
