It's part of the official discourse.

It's not about wealthy people alone. You need staff to clean retirees sh!t (literally) in a country where the median age is 42.3 and rising.

France overspent in the 2000s and 2010s due to populist politics, and now the chickens have come to roost. Something needs to give in France, otherwise it'll become an Italy 2.0.
