Well. the internet is both the issue and the answer in some ways.
Today people have more power than ever. but know very little.
Go back 100 years. and few people had power and those that had often put time into understanding it.
And the normal people most likeliy didnt know to much. but those 1-5 things they knew. they knew 100%.. today. all people have a hand in power. and "know" many 100 of different things. but they dont know any 1 thing really. they only know a little about many things.
They use a little information as their choice to form a decision. make a choice. and that is often wrong. because things is not just one thing, and to understand them you will need a deeper meaning.
And that lead to so many problems where people actually work against what they want. but because of human nature get stubborn in defending it. instead of actually learning it...
And that inturn lead to things that these people think will help them, give them more. like Brexit, or PiS in poland. but if they knew more about those things, they would see it actually end up costing them. from money, freedom security and everything else. all those things they think they secure, they end up pushing away because they dont really know or understand the subject on what they vote through.
That make it very easy for a few people to use that to gain power. because the best way to sell something is by fear, have always been, and people that know little or is not educated in something is more likely to be carried by that fear and used for that.
Fear sells better, even lies.. it can be super stupid but if you play on peoples fear you can make them believe that what you say help will help even though it actually only further what they fear.
Its all with human nature.. and all the flaws in that.
Human kind have never created anything perfect. and our fantasies often destroy the world. from invisible lines in borders, to religion and race. things that isnt real. and dont matter. matters because human kind make them manifest.
We have no good way to lead or follow. because man is to flawed. and if you follow all, you will get to a bad place. if you follow one you will get to a bad place.
As one once said.
Democracy is the worst form of goverment. Except all the others.
