1) agreed. In the US at the moment disparities seem to be increasing. Not universally around the globe, but here certainly.

2) that's what I was getting at in my response.

Low IQs aren't caused by subjective disparity but can be influenced by absolute poverty: ie not having enough food in childhood. So while a poor person today is much poorer than a rich person today in relative terms in absolute terms they are quite a bit better off than a poor person of a hundred years ago with relation to things that are known to affect IQ (nutrition, disease, pollution, access to stimulating materials, etc).

You mistake concerns about the content of the entertainment for something else, it seems. I don't have any objections to video games; I do object to the violent, misogynist content of many of them, for instance.

Many people have been trying really hard to find a connection between violence in video games and violence in real life and so far it has failed to materialize.
