@Baruch et al.
Do you understand the economic policy here? More elementary, do you understand that what's happening here might be economic policy?
I personally don't know exactly what is going on, but in the typical economic policy that Fiscally Conservative Politicians tend to adopt, is to address the "living wage" vs social programs issue. This is one of the major sticking points (for all people, not just Conservatives), that basically looks at how much can a breadwinner(s) earn at a job vs programs.
Now someone with a larger family needs to earn alot more than a single parent with one child in order for it to "pay" to work and not get programs. This is not up for discussion. It is fact.
How would you encourage the large family to work? This is one possible way. If you lower the benefits, and now a job that was below the "benefit package" before, is above, maybe the breadwinner will take that job offer.
I am no means saying it doesn't affect people in our community, but I don't think he is targeting Jews. Maybe, just maybe, he is targeting the segment of the population that currently needs to make more than they can in order for it to be more profitable to work.

PS. Please keep in mind that employers, unlike the government, don't pay more if you have more children, and as such, while maybe you feel that they should cut the amount per hungry mouth, it won't have the same effect given the employer "issue".
