I think part of remedy is promoting an informed electorate. I imagine this would start at the level of schooling with promoting critical thinking and instillation of democratic supporting virtues (like always vote)
I agree with you, but the problem with this approach is there a vocal minority (in the US at least) that vehemently opposes this as it hurts votes for "their side". The last thing they want is an educated, critical thinking, populace. They want people who will fall in line, and do as they are let to believe.
While I inferred a particular angle from this comment, I realized that it actually works for folks across a broad spectrum of political leanings. It's a Rorschach test.
I would argue that there are two such vocal minorities.
