Why is education important? Can I suggest we compare two countries singled out in the article as 'could do better's - the USA and UK, and their recent democratic decisions. Compare that to Canada's cabinet, who, for example, has appointed someone with a PhD as minister for science [2], a doctor as minister for health [3] etc etc. I don't think I need to give examples of Scandinavian countries which regularly top the rankings for both wealth and pay equality.
Maybe a population where the country has valued education are less likely to say they "have had enough of experts" [4], more likely to respect the knowledge of a specialist, and more likely to have skills which are capable of transferring to the changing work market.
The problem is that investing in education has its pay-offs 20-30 years down the line, which is why, even if we believe in education, governments are reluctant to actually spend the money on it.
