Because maternal deaths have plummeted since the mid-20th century. With prenatal health care, delivery is often safer than abortion for the mother, and certainly safer for the child.
Do SOME few women kill themselves attempting to abort? Sure – as do others kill themselves for other reasons. Much as I would like to, I can’t see that ALL suicides can be prevented. Nor that ALL death by self-administered abortions can be stopped.
As far a children living in poverty, Leftist always bring up the “it costs SO much to raise a child to adulthood” trope. Their numbers never seem to have any realistic relationship to the reality of real people’s lives, and completely ignore the fact that, for subsequent kids, the cost is less, as most of the baby stuff is already in the house, and – other than those cute little dresses – kid’s clothes can be used by the next kid. Or bought at a resale shop.
Funnily, the Left never allow the argument that illegal immigrants generally require subsidies for their kids, thereby reducing the money that might keep American kids from growing up in poverty. Poverty for Americans is hunky-dory for Leftists, as long as it allows them to bring in more Dem voters.
I’ve pretty much given up on expecting Leftists to use logic, reason, or principles.
