This article by Christopher Caldwell, The French, Coming Apart, is a fascinating look at the French political landscape, and its impossible to not draw parallels to here in the US.
In France, a real-estate expert has done something almost as improbable. Christophe Guilluy calls himself a geographer. But he has spent decades as a housing consultant in various rapidly changing neighborhoods north of Paris, studying gentrification, among other things. And he has crafted a convincing narrative tying together France’s various social problems—immigration tensions, inequality, deindustrialization, economic decline, ethnic conflict, and the rise of populist parties. Such an analysis had previously eluded the Parisian caste of philosophers, political scientists, literary journalists, government-funded researchers, and party ideologues.
Guilluy is none of these. Yet in a French political system that is as polarized as the American, both the outgoing Socialist president François Hollande and his Gaullist predecessor Nicolas Sarkozy sought his counsel. Marine Le Pen, whose National Front dismisses both major parties as part of a corrupt establishment, is equally enthusiastic about his work. Guilluy has published three books, as yet untranslated, since 2010, with the newest, Le crépuscule de la France d’en haut (roughly: “The Twilight of the French Elite”), arriving in bookstores last fall. The volumes focus closely on French circumstances, institutions, and laws, so they might not be translated anytime soon. But they give the best ground-level look available at the economic, residential, and democratic consequences of globalization in France. They also give an explanation for the rise of the National Front that goes beyond the usual imputation of stupidity or bigotry to its voters. Guilluy’s work thus tells us something important about British voters’ decision to withdraw from the European Union and the astonishing rise of Donald Trump—two phenomena that have drawn on similar grievances.
If anyone with more direct knowledge of French politics would comment on this, I'd love to hear it. I searched briefly and didn't find much to contradict this article.
