Do they realize, however, that in chutz la’Aretz they won’t be able to stay in kollel forever as they do in “the evil Zionist Israel”?
You’re kidding right? You can learn in Lakewood forever just fine.
Also, you’re missing half the point. Many of the chareidim would want to work, but they are not willing to go to the army. Observe the American chasidim–who are just the same and share the same rebbes with the Israeli ones. The American chasiddim almost all do work, and the Israeli ones would do the same if they didn’t have to be in the army to be allowed to work.
They don’t avoid the army in order to learn; they learn in order to avoid the army. A little fixing of the army would go a long way to solving the problem.
