What caused the demise of the traditional family unit?
Greed. And it still continues today. I'm climbing up on my soap box. Years ago, the wife stayed home to raise the kids and was at home when they returned from school. In almost all cases, "Mama" knew where the kids were and what they were up to - for the most part. The husband worked to bring home the bacon and provide financially for the family. There were no credit cards so most people saved up for the things they wanted to buy and were patient enough to wait until they had saved the money to buy that special item. Along came credit cards and they were so easy to obtain and to use that many people began to live outside of their means and living the "big" life that normally was out of their financial reach. Their debt grew and grew and the next thing you know, one income was not enough for the average family. This is when the wife began to work away from the home to generate more income to pay for all the "toys" that the family just had to have to keep up with the Jones family down the street. We must all put on aires and show everybody how "well off" we are. Because "Mama" was not at home now to watch the kids, they began to get into things that they normally would not have because they were being supervised. Soon all of the family members were going their own way and even mealtime was not a center of the family any longer. This is when the family unit broke down and everybody began to focus on the "me" aspect instead of the "us" aspect of family life. IMO, it was all because of greed.
