Ok, bit of a sweeping generalisation, point taken. As Mason says, correlation between education and informed voting decisions is pretty well documented. Education isn’t necessarily about schools or higher education and qualifications, it’s about world views, understanding of different cultures, awareness of the impact to others, exposure to life beyond your own bubble. The more of that you get, the more likely you are to vote in a collective, humanitarian way. You only need to look at a political map of the US to see the effect.
