"that the children shouldn't exist, you've lost me." - I'm not saying children should not exist. I am saying in many locations for many people, I think it's more of a choice against putting children in harms way.
- also 'what themacguffinman said' in this portion of this thread!
"lot more room to maneuver for many childless couples from a purely practical point" - I agree, and some may be on a path to success, for many it's you against the world and the world is really good at keeping you down/in debt / out of safer places, etc.
So I have been helping some children, a couple as official fosters for 6 months or so, and another non-official for 10 years or so. We/they have moved to cheaper which is safer in some regards (better schools) - and less safe in others.
In this process I/we have sacrificed career and portions of career (partially 'for the children') - closer to family would not make any of the things better, but that may change around age 16 - to some degrees.
We have lowered our standard of living and sacrificed a previously really fun lifestyle.
My motivations for children has always been to provide a safe environment where they can learn well. This is much easier if you make 250k / year than if you make 50k.
While I know it's possible to sacrifice and ask for help, and certainly there are safe places to raise cheaper, say some towns in Alabama - but it's hard to figure out all about the schools / towns / pollution / etc etc until you are in it.. and moving is expensive.
I was blessed to be raised in a place that had sidewalks and neighborhoods safe enough to walk / bike / bus anywhere anytime. At that time, in that place, it might have been considered abuse to keep a kid inside.
These days we have places where (I believe it's still the case) that you could be arrested for sending your kid to the park (it's not safe).
Being in a safe place is not just about affording childcare. It's about being able to afford good food, go organic as much as you can, avoid BPA, microwaving plastics and more.
It's about safe streets, safe schools, after school safety, and so much more.
Like I said my original comment - in some places for some people this is no problem, yet in many places in the US 'all the things' are less safe these days, and in many cases quite dangerous/toxic truthfully.
I've heard of some interesting safety nets for challenged children in California, and I've witnessed those heartfelt 'the village / church helped X do Y' - but we don't have the same state-paid-for child help here where I am, you even get kicked off food stamps when you get a raise to 11.30 per hour here.
If I had a new kid today I don't know what I would do. Probably look at going to portugal or something like that (much research would be needed to really pick a place). The days of assuming that staying in the US provides top notch safety and education are long gone imho.
15 - 20 years ago I was still cautious about having kids, not knowing where I could afford a safe growing-up environment. 10 years ago I still believed that the basics like safe water and good educators were guaranteed across the US.
Today I know more, and more of the things I worried about back then are less safe today, and the costs associated with escaping those things are higher than ever.
So I still feel that "I don't feel it is right to suggest the choice is putting themselves first - at least not in all circumstances, and I'd guess it's not the main factor in most of these conscious choices." is true.
Surely there is somewhere in the US where these concerns are not so paramount, and for those that have other circumstances with family/church/etc, different for sure.
I'm in a fairly modern, popular, growing city / burbs, and the basics here are not as safe as they should be - and I don't see much of that changing anytime soon - unless you can afford to get to brentwood/franklin, I think you'd be better off moving much further away for child safety.
Sure you could keep them inside 24/7 - homeschool if you have a partner and things like that, rice and beans etc, if you had to, I get it's possible, and so kids should exist.
I still feel it's easier to make that choice when you either make lots of money or have found a small safe community with options - of which I don't think there really are that many for most people here anymore.
