As for taxes, I think repeated studies have shown abortions more than pay for themselves when it comes to tax dollars.

You'll notice that most anti-abortion people also have strong feelings on the welfare state and other similar things. AKA the place where all that money ends up costing people more.

Same with strong feelings on preventing the pregnancy in the first place. Whether through outdated means (abstinence education) or cultural (ending the "sexual revolution" induced hookup culture).

Its not like people are just hearing about this issue two minutes ago and haven't had the time to think through consequences. Most of them just have wildly different perspectives on many things that all are relevant factors to this singular topic.
