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.

There are two completely separate issues that dont make sense to combine unless you just want to use it as a weapon. The question is if the fetus is "sacred" and deserves rights, if so then you cant kill it.
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.
