Please note first my use of the word "voluntary" below.
Consider: How about a $-cash incentive to accept VOLUNTARY sterilization by a gov't.-dependent woman after her first taxpayer-supported child?
It is indeed terrible that these babies immediately have little chance in life. Why the perverse benefits incentive to subsidize even more of them?
Unless the mother is truly afflicted with some condition that prevents her from taking care of herself (alone) without my gov't.-coerced compassion, the miserable life that results from stupid choices she and her family have made can remain their miseries. Conditions that can be remedied if she/they want to.
My generous church supported by my generous contributions, perhaps, can help.
