Land of the free my ass. It's a nation of lunatics ruled by fear.
I grew up in the 50's. I had a happy and healthy childhood. But by today's standards, every relative of mine would have spent their entire lives in prison. I lived in Philadelphia, and by the time I could reliably walk I was running short errands of a block or two for my grandmother. "Go get a head of lettuce from the greengrocer, dear - have him put it on my account." By the time we moved to the suburbs (I was six) I was walking a mile or two to school. At eight I got a bike, and in summer roamed the entire town, out of adult supervision for most of the day. By ten or so I had a rail pass, and visited nearby towns (usually with a friend) to go to book stores or hobby shops. Note that I purchased, and flew, "dangerous" hobby items like model rockets.
Most damning, when I walked home from school - starting in third grade - I was home alone for a couple of hours before my mother got home from work. No one thought anything about it, or anything else mentioned above. I am so, so sorry for people currently experiencing childhood - they'll live their lives in coddled fear. No wonder they expect the government to protect them - they have no idea how to live their lives themselves.
