French farmers marched again to remind their country and the world of their terminal crisis. Without official permission they marched at dawn, with their tractors and trucks, along the Champs-Elysées, the main avenue of Paris.

The place is symbolic: the Yellow Vests arrived there, an impoverished and angry middle class, which destabilized Emmanuel Macron's government for two years. The farmers' anger exploded last Saturday at the Agriculture Show in Paris, when a group did not allow President Macron to inaugurate the exhibition.
