Why blame Mr. Rogers or the media. Blame society for forcing both parents to work just to keep the bills paid and the kids clothed and fed. In the 60s we saw some two parent homes where the wife started taking extra work to save up a stash but in the 70s it became a necessity just to stay above water.
When all is said and done, it's because governments would rather fight than actually work towards diplomatic ends. Throw in corporations taking advantage of whatever they could to push the market to its fullest. In other words, what the market could bear. They kept on squeezing then and today they are squeezing harder through deregulation and having the foxes watch the henhouse.
You are going to cater to the Koch's one way or another.
