There is a correlation to increasing tv watching and decreased social club engagement. By social clubs I mean bowling clubs, skating clubs, 4H clubs, knitting clubs, quilting clubs, book clubs, etc. Whatever other clubs people used to do back in the pre modern television era.
Being a part of these clubs connects you with your local city. It encourages real social relationships. If the club membership is diverse, you are exposed to people of different backgrounds, experiences, and races, which decreases racism and xenophobia.
All of this will increase the amount of trust we have for random humans. And that correlates strongly to how well government is working for us.
This could also be fueling why the US has so much hostility in politics now. What if we were in clubs with people of different political viewpoints? You like these people, and you disagree politically. I think that would change things.
So please, do your part and stop watching so much bullshit on television. Sure, a few good movies and shows every once in a while is understandable. But really do you need to watch all these new TV series and every single made-for-netflix movie??
