While the reason is honorable, I can't help but think this is an attack on poor/middle class people. Traveling by train in France is quite expensive, and very annoying some times (I live in a lost country-side, and if I want to travel to my parents, it's a three to four train ride, taking about 8 to 10 hours). Ok, plane wouldn't help in most cases either, but the train offering got a lot gutted over the years and it's not going to improve.
