While I agree with you at some level, I can't help thinking of the Amish. They impose plenty of restrictions on themselves and still manage to flourish. There must be a way that is different than simply accepting "progress".
Amish have an overall fertility rate around 6, which is why there are now almost half a million Amish in America alone. They had less than half that in 2000. In a few decades, they'll number in the millions. If people don't start having babies then groups like the Amish will take over the world, very much turning "the meek shall inherit the Earth" into a completely fulfilled prophecy. In some ways it's perhaps even a self fulfilling one if it turns out that 'non-meek' behaviors result in unsustainable societies.
