Let's not forget, the largest crime spike in modern American history was right as the boomers hit prime crime committing age. So lets not allow nostagia to convince us that the past was some golden era of high standards and raising children well.
Crime rates are still way below what they were in the 70-80s.
The formula is more complex than just crime data. Societal awareness plays a huge role. We like to express how awesome we were back in the day and how kids are soft today, but our awesomeness was fueled by naivety. The cautiousness we see today may actually be the correct response to the information we have and it may have been us that were incorrect based on ignorance.
