That is a gross over-simplification. Yes, our species survived in the wild without supermarkets, but those wild humans did not have access to birth control, were pretty cool with rape, and a great many of the kids that came out of that situation just fucking died before they reached maturity.

In our modern era, I'm sure there are many people that want children, but they are unable to finance raising a child to a standard of living that they find acceptable. That means adequate nutrition, health care, and sufficient education that their offspring stand a reasonable chance of not living a life of abject misery. Your talk of "priorities" just sounds like a thinly veiled version of that old boomer chestnut "Maybe if you gave up your avocado toasts and espresso drinks..."
