Raising a child costs between $13k[2] and $35k[1] per year in the USA – depending on where you live and who you ask.
With a minimum wage job ($7.25/hr) you need to work about 5 to 13 hours per day to make that much – before taxes.

I'm not advocating insane gop'ers, it's up to the woman, but they'd say it's about not killing a kid. They'd go up for adoption which is very successful in the US. They are insane assholes but this is a pretty weak argument IMO.
