I don't know what happened between then and now. I don't have kids so I don't know how people make decisions about them. I know a big part of it is fear of child abductions and getting hit by cars. I think it's just an irrational fear of those things (or bullying or using drugs) that slowly led to tightening the leash on kids. Today I rarely see kids doing anything in public without a helicopter parent within 50-ft. One of the middle schools I drove by allows one child to leave the door, go straight to their parents car, before the next car pulls up. They aren't even allowed to walk home unsupervised.
