DbT‘s editor is the farthest thing from an expert on French society, and has not set foot on French soil since 1987.
Nevertheless, since the automobile and its French accoutrements play such a central role in the thing, DbT hereby offers its official guess:
The Yellow Jacket movement is a rightist version of #Occupy.
Meanwhile, the thing, like #Occupy, has neither leaders nor a coherent agenda, and is fueled by Twitter storms and pose-striking. Hence, it won’t last, and will have little effect.
None of which is to excuse Macron, who is a yuppie dunce bent on repackaging dangerous (witness the neo-fascist tendencies afoot) Reaganite dogmas.
Trying to sustain an automobile-centered way of life, however, is a losing gambit, in any form. Capitalism’s #1 machine is simply unsustainable under the given laws of physics, which are rather strict.
