Please take a look at what happened in Athens a few thousand years ago. You'll see that even then people were susceptible to fear mongering and manipulation, so in effect the real power was in the hands of a few. People has always been stupid, there's no way around that, sorry.
No, you have to understand how human nature works. Unfortunately, it is much easier to get people worked up about populist issues than about something that matters. I think the record speaks for itself.
