I once had a discussion with a Democratic activist in NY asking why didn't NY cut its bloated bureaucracy. He told me that if this were done, there would be riots all over the city. In other words, if the spigot were to get cut off, the steam would build up and explode the tank so to speak.
Correct.
And this will be the way out for France too.
Jobs cannot be created overnight in the private sector, and trying to pry free the rigidities of the French labor law would provoke labor riots and a general strike which would bring down the government.
Government employment, by contrast, would get people into jobs. They're already earning welfare and unemployment benefits, so it would not cost the state much more money...and they would start paying taxes and get off the streets.
The Beurs need to be working, at real jobs, all day, all year. Do that, and the problem of idle hands largely vanishes.
