The French protests although primarily about fuel taxes, are also a protest about a lofty elite that are dismissive of the ordinary people, who they feel have no conception of the problems faced by poorer communities. The French have always taken to the streets, really the republic was borne out of violence. As far as disillusionment with politicians per se is concerned, it could be happening anywhere. I read in the Times earlier this week, one of the reasons that Brussels is disinterested in pursuing further options with Britain is because there are bigger problems in Europe, France and Italy in particular.
In an article in The Sunday Times magazine last week with Bruce Springsteen, a lifelong democrat, he said that he felt that Trump would serve a second term because there wasn't anyone from his party who could reach out to the poor and disenfranchised. I think politics is shifting and politicians who don't engage with sectors of society, such as the "baskets of deplorables" Hillary Clinton and the "bigoted woman" referred to by Gordon Brown, will do so at their peril. Not wishing to be partisan, it's across all parties, they are all too transparent and the electorate are aware of that.
