WELFARE BENEFITS. Are given to everyone. They are very common in Europe, increasingly common in the USA (Obama is pushing them, the Republicans oppose him). The idea that to a certain extent everyone, regardless of who or what they are, should receive a certain package of benefits. A problem is that (according to conservative economists) they remove the incentive work. Frum Jews generally place a great value on having time for learning, time for family activities (which include learning), and work schedules that avoid hassles – so the effect of welfare benefits is to discourage work. The same has been observed among goyin in general (note the debate between Romney and Obama on these matters). Giving welfare benefits to one group (Arabs who support Hamas, Jewish gangsters, Jews who chose to spend all day being high and playing computer games, etc.), and denying to another group (Jews who spend all day learning Torah and caring for their children), would be considered discriminatory.
KOLLEL BENEFITS are money paid specifically for learning in kollel. This is really a (poorly paid) job, not welfare. If the zionists want to limit them to people who serve in the army it is less controversial – similar to a donor who supports Satmar who doesn’t want his money going to zionists.
