Don’t know about the original poster, but the way I figured it out was to go and briefly immerse myself in the environment of the poorest of my countrymen, and I also spent a little time talking with old Irish ladies living in British hedgerows when I visited the UK.
You know, in Philadelphia there are six layers under center city. Down there, the topside world’s rules don’t really exist. If you see a policeman, you better run, because they aren’t going down there to help people.
I’ve lost track of the number of times people have used numbers and statistics to “prove” what I’ve seen with my own eyes doesn’t really exist, though. You have to go there, and hope you survive the experience. Try Liberty Avenue in Pittsburgh at 4am, or the alleyways of the Port Authority in NYC around 3ish.
