Eh? Population growth is largley driven by psychoogy and sentiment of the population. You can see birth rate drop in the US now because of rising cost of living for example. The argument may still hold true but population growth is not exponential, it can drop as much as it can rise. Longer life span also means increased social burden and costs. Having to care for parents through their 80s and 90s means you can't afford as many kids as you could have afforded. And it also has to do with expected quality of life. Middle class in the west is has more expectations of what a good enough quality of life for Children should be as opposed to most if africa or parts of India.
