For decades on end, members of the lower socio-economic strata have been voting for leftist parties in many Western countries. These conventional class-party ties have come to an end, puzzling many political commentators. Instead of voting for a leftist party, the working classes’ preferences have shifted towards populist parties like PVV, VlaamsBelang, FPO, and UKIP. In this lecture, Peter Achterberg will discuss why this is so. More specifically, he will discuss three questions: 1) What explains the rise of radical right-wing political parties? 2) What explains the voting preferences of the working classes? And 3) Why have these changed in time?Lecture for Tilburg University Alumni: March 16th
