I don't assume that. I think the human population is underutilized, mismanaged, and kept barely above slavery in many parts of the world. I think the outrage of overpopulation is being manufactured by those who hoard resources and demean the labor of people.
Rather than giving the resource hoarders more control over our reproduction, I'd like to try more cooperation and less competition, and try to distribute resources more efficiently and effectively for a larger percentage of the population. No more food rotting on docks because there's no profit in getting it to starving people, which will make them healthier and more able to continue their own prosperity. I'd like to start a cycle like that, because we know where the "overpopulation" cycle leads.
