Ian Bremmer: The problem is not Trump. Trump is a symptom. If the problem were Trump it wouldn’t be happening in other places around the world. We actually see all sorts of countries, advanced industrial democracies, where people are getting angrier and they’re voting more and more against the establishment. We saw that with the Brexit referendum, which was before the U.S. presidential election; We saw it in Germany with the rise of the Alternatives for Deutschland, an actively Euro-skeptic party for the first time since World War II; We have nationalists in the German parliament; We saw it with the recent Italian elections where they threw out all of the establishment parties and instead it’s the Five Star Movement and the League, again Euro-skeptic, anti-immigration, populist political forces. This is very unusual and it’s not coincidence. So why is it happening?
