Yeah. Frankly, what our society truly needs is more of this. Ecology/biology calls it alloparenting. Indigenous and other cultures call them "aunties and uncles". Liberals say, "It takes a village".

Culturally we are suffering the consequences of post WWII propaganda glorifying becoming a parent as a means of signifying status (among other things). It was a push to increase the population after so many died, but also to expand economies and trade.

Problem is, as you well pointed out, not everyone is fit or suited to be a parent. That has consequences to the population at large in the next generations.

You go back before all that propaganda and you might have been pitied for being an old maid or a "leftover bachelor" but nobody lost their damn minds about it. You weren't charged with being selfish or irresponsible (unless you were monied). In fact, most families depended upon at least one of their children not procreating to help out with aging parents or a sibling who had too many children or a disability/injury.

In other words, you might have been pitied by some, but you were also seen as valuable, necessary, a blessing.
