Just wanted to point that the idea is to offer an alternative job, not to force nobody to do anything. Currently, in a lot of countries, unemployment payment just run for a while and only if you worked before. Then, if you can't find a job you have a serious problem.

Job guarantee also "force" a minimum wage in the economy without need of big controls. It can be though as another automatic stabilizer.

Anyway, maybe you are right. I haven't made up my mind about it yet.
