this is not that easy to explain, so i'll try my best in english language.
I think these rioters are dumb and ineffective if they really want to change something. They target workers in order to make them unable to work instead of targeting government, and that's dumb and not couragous.
Yes, it's not a big deal to work 2 more years.
There are 2 mains problems in France.
At 1st, low profile workers think that CEO/managers all cheat on them. They think they hard work for a very low wage although managers aren't doing anything for 3-10 time their salary.
2nd, it's harder than any other country to find a job, because it's harder for a manager to fire/release a worker. In France you cannot (officially) fire a man like that.
I'm not sure to explain well, but it's like a vicious circle because there's no flexibility.
btw, saying that every french is lazy is as fair as saying every american is dumb and arrogant...
