I agree with a lot of your observations, especially about music and peanut butter, but it turns out violent crime peaked in the early 90s and we've seen a significant reduction in the years since. If you're much older than 50 you have a better argument, but from a crime-reduction point of view, we've improved dramatically over the last couple of decades.
A few quick facts I pulled from the data on the FBI's Uniform Crime Reporting Statistics site
In the aggregate, violent crime is at about the same rate it was in 1973:
The homicide rate is the same as it was in 1965
Property crimes are at the same rate they were in 1968.
