I grew up in Southern IL. We lived out in the country and NOBODY locked their doors day or night! My Mom and Dad were married and Dad went to work EVERY day! My Mom stayed home to take care of my Sister, Brother and me. She did not work until we were all in school and then she worked only part of the day and was always at home when we went to school and came home.
Today people everywhere lock, chain and bar the doors day and night! Most households in the "troubled" areas are single parent or neither parent EVER goes to work! To date the USA has spent over 22 Trillion dollars and counting to improve many lives and to stop poverty! IMHO today it is much worse than it ever was when I grew up. Nobody thought back then that they needed to carry a gun on them when they were outside of their home let along inside their own house. So to quote what obummer said, "When something does not work. We need to change direction and try something else!"
But I say perhaps we need to go back to the basics and the same values that we had 50-60 years ago!!!!
