I think it may be acceptable to ease the tax burden on child bearing marriages. The only thing that we should not be doing is subsidizing child bearing if the family cannot afford to support itself. If you cannot support yourself, then you should not be either starting a family or expanding a family. This means that if you are receiving absolutely any public assistance whatsoever from any government agency, then you should in no way be eligible for any expansion of benefits for any new children. And this should be permanent.

Where I am at, once you start receiving benefits, you are limited as to how much cash benefits you may receive. This is forever, once you exhaust this fixed amount you are not ever eligible for any more. The same should apply for child bearing. When you enter any public assistance program, then from then on, you are not ever eligible for any additional benefits for any new children. If you are able to secure enough self support to be ineligible for public assistance, but are required at some point to go back on public assistance, then your status should not change, you are not eligible for any additional assistance for any children you may have added since you were last on public assistance.

When people have children while on public assistance, this is government subsidized poverty and has to stop.

And nobody who is receiving any public assistance should ever receive any kind of tax benefits. They are already getting tax benefits.
