I think it is an expression of the same discontent as Brexit and Trump being elected as POTUS. It is those who just managing (or not) financially being hit again by a policy dreamt up in a metroplitan bubble, without any concept of how it will impact on those who don't live in areas readily supplied with public transport and where driving is a necessity.
I think they have wrung some concessions from Macron, but he is an Enarque and a banker, with little or no comprehension of how the other half live. I think if they continue protesting and the violence used against them increases then perhaps the UK might see that this is how protests are put down in the EU and that we perhaps don't want to go down that route.
I hope they wring more from him. I hope that others see that they are not alone or isolated in what they feel and that it is reasonable to express this. I don't think that those within the peripherique, the M25, or the Beltway (and the Ring for that matter) have quite yet grasped how profoundly pissed off the people outside those bubbles are with being told how they should think and feel, and that they are beyond pissed off with their very real concerns being dismissed as ignorance.
This is why Trump will get in again, why Brexit (and the anti EU sentiment that drives it), and the dislike of the political 'dynasties' in Washington won't go away. Until the concerns are addressed, or at the very least acknowledged as being valid and real, then we are in for a bumpy ride.
