There are two different vectors here... education and intent. Is that highly educated person attempting to educate others or deny them an education? And do they intend to form an abusive or a cooperative relationship?
Some highly educated people seek to deny the education of others to maintain their power and control over them; seeing those other people as their farm animals, to be used and bred, and not to be educated. There is a reason "Animal Farm" was so accurate an analogy. I remember a horse that knew how to flip open gate locks, and the horses would follow him out into a field. It wasn't a problem because they would come back to get the evening's sweetened grain, but what if they were smart enough to get beyond the field and into the wild? And what if this was a farm where the horses delivered a daily product essential to the farm's economic output? I was just a horse handler for a while, but I could just as easily taken the position of being an enforcer, with the role of stopping that horse from that activity, and of denying any other horse the education enabling them to gain freedoms. I could be using coercion to regain control, and talking sweetly to the horses, "come back to your stalls, there is benefit to being enslaved", while I cut the sweetened grain rations for the troublemaker.
Democracy fails when a group of educated people is able to control an uneducated group and maintain that control by denying education and representation. You can look back at the slave holders who wanted to obtain votes based on their enslaved populations, or you can look at the "they want immigrants to gain votes" chatter. It is all the same thing... groups of highly educated people are in direct political competition, attempting to control masses of less-educated people in order to gain political power. There are truths in what either group is saying, but there are also falsehoods. The importance should be on the intents of the individuals within the groups.
