Nice elaboration.

I would like to add one more very similar example: Brexit happened because of the votes of the older people. I can't remember the exact statistics, but the age differences were extremely obvious, with the vast majority of the people older than 60 voting "for" and the vast majority of the people younger than 30 voting "against". It's because the younger population has much better access to information and is thus much more open-minded and able to think critically. Cheers!

I know the cases. They are all linked together. It's something that we need to do in the future to prevent this. And stop using Facebook for getting news which is a bubble creator in itself.
