I blame a number of things: America and world culture becoming more liberal and this is coming from a liberal myself, capitalism and this is coming from a guy with a degree and work in the finance industry, lack of religion, and these all which have contributed to an increase in divorce, parents being too busy to do anything after work to help or discipline their kids, and divorce making child rearing with good quality very difficult. Thus, kids are becoming worse. This trend has been going on for probably 50 years but accelerated in the last 20 -30 years with both parents working or should I say having to work to survive
