And yet in nation after nation hundreds of millions are voting strongmen to lead them. If one is serious about understanding the reasons a good place to start is to stop blaming them ("entitled", "myopic", "curmudgeons"...) and make a genuine effort to understand their world view.
These are not fringe elements but hundreds of millions dissatisfied with status quo and want something to change, and are willing to give strongmen a chance. They don't care how the life was 50 or 100 years ago or that life today is 99% better. Their lived reality has lead them to believe they are leading a shitty life. Telling them they are myopic or entitled will only lead to further disconnect.
