A new study by Pew Research verifies much we already know about political extremism in America: It’s getting worse and interfering with social and economic progress. The big question is: Why?
Pew doesn’t address that question, but here’s a plausible answer: Voters are becoming angrier because living standards are falling and the middle class is shriveling. Prosperity breeds comity, but when it gets harder to get ahead, the natural inclination is for the losers to look for somebody to blame and the winners to feel more threatened. That’s been going on for nearly 30 years. Income inequality began to worsen in the United States starting around the early 1980s.
