Winnie,
1. You are half correct. Tying social benefits to going into job training is also a form of force but it can work. The same goes for not supporting schools that don’t teach subjects that form the base for acquiring job skills.
2. Teachers and kashrut supervisors make very low salaries. As for discrimination, it is in part due to the chillulei Hashem of some of the Chareidim (in particular the Pelegniks). Refusal to go into the army is also a very sore point. However, as the Chareidi sector grows employers will decide that they cannot afford prejudices (Ludwig von Mises, in his book on National Socialism, Omnipotent Government pointed out that it took Nazi terror to get Germans, including antisemites, to boycott Jewish businesses. Moreover, in a capitalist economy groups which suffer discrimination can start their own businesses, as Milton Friedman pointed out regarding the Jews in America in Capitalism and Freedom.
3. What about the obligation to protect Am Yisrael?
4. I don’t know. However, it is time that laws should be enforced one way or another. For example, slackers could lose all social benefits. If they do not believe in the Medina the Medina should not believe in them.
Gaon, who says that the PR did not believe in Zionism?
