Race riots occurred in this country because of the acute structural contradiction between the white settler-nation and the other nations; these contradictions have not been resolved by radio and TV in the interim. We will see more of these riots in the future.
But I think is that more people would not have been OK with that level of violence and destruction if they had a chance to actually see it, rather than presented through words on a newspaper.
The point of people who think that our society is de-humanized is that when your society was forcing you to work in a farm or to go to war, you didn't have the free will to be alone. You were indeed "forced" to engage in activity involving using your body to do meaningful work (farming), do things with your peers (war).
The family/social unit in tribal cultures is comparably closer on many levels than families in individualistic/civilized societies.
In the former, survival depends on community cohesiveness, in the latter, survival is a game of everybody against everybody.
10,000 years ago, you would live in a tribe. If you were not popular among your tribe, it is likely you would be either exiled and forced to live in solitude and die during winter or be constantly subject to violence.
2,000 years ago, you would live only to work in a farm or be in a state of perpetual war. To make things worse, literacy rate was something around 0.001%, if you were lucky.
1,000 years ago, you would be essentially doing the same while dying from a plague. There was no sanitation of any kind.
200 years ago, you would be working at a factory and going to war every 30 years.
100 years ago, there was no radio or TV, so you still had stuff like this: https://en.wikipedia.org/wiki/Tulsa_race_riot
About 60 years ago women were predominantly housewives and were vulnerable to all sorts of abuse.
So no, right now things are better.
