I agree with that. Part of the reason for the resurgence of right-wing populism in the U.S. and Germany and Europe is that the lessons of the 20th century’s experience of fascism are passing out of living memory. In the U.S. the situation is even worse, as history and civics education in public K-12 school have never been a priority (except for rah-rah American exceptionalist boosterism). But even in Germany, which took on the educational burden of collective responsibility with particular grace and humility and vigour, we now see the rise of the right-wing bigots riding the wave of anti-immigrant sentiment.
In the U.S. and (in a different way) in Europe we are all also coming to the end of the postwar economic anomaly of general prosperity and a large middle class that was anathema to right-wing populist movements and parties like “MAGA” in the U.S., AfD in Germany, Front Nationale in France, etc. ad nauseum.
