The documentary La Cravate totally gobsmacked me. It is about a young supporter of the Front National during the presidential campaign of 2017. You should immediately hate him, but you can't. He's a nice guy with all of the wrong ideas, but as the story unfolds, you understand why everything went wrong. It was basically our fault for not helping him when he needed support. Since his life went wrong, it was basically normal to blame everything on the usual people -- immigrants et al.
I thought that he was incredibly courageous to allow himself to be filmed in every aspect of his life by leftist filmmakers, and I will even tip my hat to the Front National for allowing the cameras to follow him almost all the time. They never do this, but I suspect that the Amiens section of the party was not under strict surveillance at the time. His total dedication is shown, as well as his hope to rise in the party. But then he is passed over for other newcomers and he becomes disenchanted, although it doesn't change his political views. He finally admits a dark incident from his past, and things become clearer. At first he says "don't put this in your film" but later he changes his mind which is why it is part of the film.
Since the documentary was made, he has left the Front National to join a useless dissident splinter group, but after 90 minutes, I feel that I could sit down with him and discuss politics, and that is something that I always thought would be impossible.
Unfortunately, there are no trailers available with subtitles.
Sounds most intriguing. I also found the concept (don't speak French) as you explain it particularly pertinent, having just taken an online test to determine my political leanings. More than one of the questions addressed precisely that idea of how much the government owes its citizens in terms of support, both economic and otherwise.
