I know we're on hacker news but I don't quite get how you put "technology" in these lists. The trend in Europe is very, very obviously about the immigration crisis. Which, if not racist, is at least a nationalist issue.

Globalization is a popular issue because it can also mean that national interests are overpowered by international pressure. But you'll also find resistance for that on the left (because the left never liked globalization in the first place).
