Trump is doing this in America. Those of us with some oversight from history can see it happening.
Read this brilliant, long essay in the New York magazineto understand how Plato described all this, and it is happening just as he predicted.
Trump says he will Make America Great Again, when in fact America is currently great, according to pretty well any statistics.
He is using passion, anger, and rhetoric in the same way all his predecessors did — a charismatic narcissist who feeds on the crowd to become ever stronger, creating a cult around himself. You can blame society, politicians, the media, for America getting to the point that it’s ready for Trump, but the bigger historical picture is that history generally plays out the same way each time someone like him becomes the boss.
