No offence but you are mixing socialist policies, socialism and communism - very different things; I'm unaware of any communist country which goes soft on crime.
I also fail to see how premise leads to conclusion.
If you want another wacky theory here's mine: imho capitalism unleashed (extract every single penny) leads to less time to be active in a community because people have to work more.
On another hand loss of religion leads to hedonism - satisfy the immediate needs.
Combine the two and you get what we have today.
