Maybe people are just socializing less. A study on college kids in 1979 would have been studying kids who were born ~1960, when TV wasn’t worth watching, there were no computer games (especially no violent first person shooters), there was no internet, and people had to socialize a lot as there was nothing else to do. Maybe people are more isolated and individualistic today in part as a result of these things.
I think that’s more the reason. I know my mom told me once that in southern Baltimore, people used to be out in the local park all the time during the summer (and at night when it was cool). But, then came air conditioning, and everyone was inside theatres, libraries, and eventually their own homes. So, that kind of started the split up of society. In the 60s, transportation was much more available and people moved out further from each other. ‘Women’s Rights’ also effectively encouraged all women to have careers (regardless if they were currently raising their kids). In the 80s, you had “latch key kids”, or kids that came home to no parents. In the meanwhile, you had all sorts of conviences come along (in fact, it reads like a book on “How to Destroy a Society” -
Microwaves - just tell the kids to pop in a pizza.
Computer Games - Kids sit and play for hours on end (not every game was multi-player, either)
TV in every room - Now family is split up into their own rooms and don’t talk to each other much except for the weekends.
Hundreds of TV channels - So many choices that it’ll be bound to keep them occupied.
Phones (including cell phones and iPhones) - Gives the false security of being connected even if you live 500 miles away.
Then there’s the work culture that says “You’ve gotta keep moving up! You’ve gotta 'compete with the Joneses!”. Because of that, there’s no time to have any kids. I think this is the reason for lack of empathy - there’s very little children for kids to interact with during the very early years (0-5), and there’s very little family time. They’re effectively “abandoned” (kind of a strong word, but it’s like virtual abandonment if you add up the amount of time without family around).
Then there’s the big McMansions people buy, and their kids (since now they only have 1-3 kids) have a room to themselves, more than enough bathrooms in the house that they don’t have to share or wait in line. Essentially entitlement.
