Babies will be abandoned whether these boxes exist or not. Thats evidenced by the fact that in the UK, a country with free medical care, a decent amount of maternity leave, free and easy abortion access etc babies are still abandoned.
Now I could (and have in the past) waffle on for ages about how better the UK could support parents, and how poverty, a shotty cms system, defunding of sure start centres etc makes things worse for parents.
But the reality is in the UK it is easier (and free) to access the medical care you need. And yet still babies are abandoned, as they are in Europe etc.
Therefore even if America legalised abortion across all States and made it free and easy to access and put in good post natal care to detect and treat PND and better maternity leave etc it still might not eradicate people abandoning their babies.
And in the meantime there are babies out there who have been abandoned who could die from cold/heat exposure etc. And so they need to be protected too.
And whilst I understand you do not like the founders anti abortion stand, something I wholeheartedly don't approve of either, this is also a woman who was herself abandoned as a baby. I don't judge her for wanting to improve things for babies in the same situation as she was in even if I do disagree with her stance on abortion.
But I think her being abandoned has more of an impact on her starting this than her being pro life. And this must be an incredibly emotive subject for her and its not that surprising she is arguing she should have had a better (safer) start to life rather than she shouldn't have been born.
Finally (and I know this is a long waffley post) I think what's important to remember about these boxes is that they also protect the mother in many countries.
It is usually illegal to abandon a baby but by placing a baby in these boxes it becomes a legal way to do it. And that important because its often the only legal way open to women in certain situations who don't feel capable of engaging with social services etc
Men can and do frequently abandon babies and get away with it. They can leave a baby in a house with a mother who is high on drugs or an alcoholic and they still generally won't get arrested for abandoning a baby even though it can be just as unsafe for the baby as leaving on the steps outside of a hospital. But women, especially women where the father of the baby is uninvolved often don't have any options unless there is a baby box. Do it protects women as well as babies in a way.
Yes a society where these are not needed would be wonderful but babies have been abandoned for centuries and I would rather these boxes were available and not used because we have improved society to the point of not needing them, rather than not have them at all. I wish they existed in the uk.
