I don’t have time for o look at the stats and provide quotes / cite sources but it does seem from what I’ve read on the topic that the more people play gore games the less violence there is in society.
If that’s true, maybe it’s also true that the more people have access to adult content the less babies we create as a society.
A society shrinking causes a number of issues.
Correlation is not causation.
The US had more TVs per capita than Congo, and a higher life expectancy. Sending more TVs to Congo probably won't do much for their life expectancy though.
Similarly, I suspect the increase in violent video games and reduction of actual violence is just a side effect of an increasingly technology driven society.
