A 10 year federally funded study showed that the longer young children spend in day care away from their mothers, the more problembehavior is exhibited, especially aggression. Lead researcher, Jay Belsky of Birkbeck College in London, reported that children that spend more than 30 hours a week in day care or pre school are harmed the most and showed behavior problems of fighting, cruelty, explosive behavior and often argues a lot. The study results, although not surprising to many, was an embarrassment to liberal and left wing groups including the NY Times which also reported the study. The liberal/left promoted the use of day care as a beneficial way to raise children, without any evidence, and has become part of their propaganda to institutionalize children at early ages and break down the family structure. The harm to children and society by the liberal/left due to their social experimenting has caused many additional problems. Many behavioral problems lead to learning disabilities and has resulted in a new phenomenon of children diagnosed with ADHD, Attention Deficit Hyperactive Disorder, and are then often prescribed medication such as Ritalin which also leads to harmful results.
