Interesting as I read this while also pondering about the same topic the other days: how much can we blame the environment? Well I believe that birds of a feather flock together because I had experiences when I thought someone was a poor innocent staying in the wrong crowd. The cases are rare and more common with young people. As adults, we make our choices. And despite our desire to believe that someone is so good so we need to pull them out of the filth, the truth is rather simple: people are the sum of their choices. Whether they admit it or not. Choices can be conscious or not. But I would be cautious if I would hear someone blaming the environment, the parents, the society, the internet etc and not themselves. Who is guilty: the one selling the box of candy or you buying the whole thing?
Depression leads to consumption. I guess this is why nobody insists for emotional education as much as for massive entertainment. Some people don't want to be fixed and healed, they want to be entertained....
