Generally poorer and less developed countries have much higher birth rates, so I'm not sure the "bringing life into paradise" reason is why people have kids.
Maybe there is a right amount of adversity. Too much adversity leaves people broken and traumatized and with learned helplessness. Too little leads to the kind of malaise you see in the most developed nations.
But it has to be real adversity, not fake or cooked up by warmongers and fascist loons. This is one reason I am such a supporter of things like space exploration. We need stuff to do that is both hard and real.
