And you clearly have never spoken to these people or actually read what they say. I quoted one at the beginning of story.

Politicians are certainly powerful. However, most of them are profoundly ignorant and they aren't particuarly intelligent. A lot of them don't have much in terms of an education. For instance, the prime minister of England has an English degree and was known for being lazy and not particularly bright. Professors who taught Donald Trump said he was the most stupid person they had ever met. He is probably semi-literate.
