This argument is unconvincing and really annoying. I don’t care about the calculus other people had to go through to have children in other times because I’m not them. Every human makes decisions based on the pressures they experience in their own life, pointing out that times were worse elsewhere is just annoying pedantry.
And of course, part of my point was I’m dubious about having a kid in America. As in, I’d be open to going expat and raising a child somewhere I think is safer and more stable.
