Gavra: Certainly there is no inherent right to subsidies in the abstract. But there is an inherent right in a democracy to be treated fairly by the majority.
And when the majority goes against its usual values specifically to target a disliked minority, that is unfair.
Here, the usual value is wanting to make a tax and welfare system that takes into account the needs of the payers and recipients. Children obviously have needs, and large families obviously have more needs than small ones. But they specifically ignore that because they dislike the chareidim. I think that’s unfair.
