I agree for the most part. However, the guy who wrote this is pro-civ and thinks we should desperately cling to this evil creation in attempt to save it. He's right, it's collapsing... but we should welcome that, accelerate it even. Civilization/agriculture is a cancer upon this earth and we all have to suffer the consequences for what we've created and maintained.
Also, I think the Alpha-Beta idea is too black and white and overly simplified. The truth is, women used to marry men for their ability to provide resources. This applied in both hunter-gatherer societies and agricultural ones. Now that food production is outsourced to a small few mega industrial producers, women can go for the top 10% chads. This is a result of modernity.
If you're smart, you learn to raise your own animals and provide your own food. Because when SHTF and the industrial food system collapses, women will soon realize that little-brain Chad cannot provide her with food because he doesn't know how to farm.
