Mdd, “the chareidim” are not on the government’s payroll, at least not anymore than anyone else in this country. That’s the point you’re missing.
Men who learn in kollel are not the equivalent of a university student. They would be the equivalent of people who are in research or who are part of a think tank. Are they considered people who are not working? No. Why not? Because what it comes down to in the end is that the secular establishment views Torah learning as a waste of time, but research as a valid pursuit. So the secular establishment has no problem with the government supporting research and think tanks, but has a major problem with kollelim.
The kollel stipend is the only one that can be classified as benefitting chareidim alone. The child subsidy benefits anyone who qualifies. It is not based on income. If you make 5,000,000 shekel a year and have 2,3,4 or 5 children, you will get the same child subsidy as one who makes 5,000 shekel a year and has the same amount of children.
And I have another bit of news: The average Bnei Brak housewife might work as a programmer, but her husband is not in kollel. He is working, too – and most likely still does not have to pay income tax because they are not making enough to cross the threshold. And the kitzvat yeladim is not what is going to make the difference.
The myth that all chareidi men are in kollel is ridiculous. Among young couples, it might very well be that the majority of men are in kollel. But not in the chareidi community as a whole.
