The first thing I think of babies in day care, latch key kids and/or kids who raised themselves. SOMEONE should do a study of the effects of kids who get dumped in questionable day care centers from age 6 weeks on up to age 5, and whether a high percentage of those kids grow up angry, depressed, hostile, anti-social and prone to substance abuse. And whether the highest percentage of kids on Ritalin has anything to do with "babies sent to day care"(not ALL---some)
