Look, I’m not making any claims on nutrition vs caloric intake. I’m using calories available per person as an analog for the amount of resources an individual consumes today vs in the past. A calorie is literally a unit of energy, so we literally have more food energy available to us today than previous generations. That’s the argument.

As a society have normalized increased resource utilization. This has happened largely with a decrease in the cost of these resources until recently. There is no reason to believe the trend of increasing resource utilization and decreasing resource cost would hold over time. Our generation got unlucky that finite resources finally started to show up in resource costs. It was like a game of musical chairs and the music stopped around the mid 2000s and generations that had not established wealth at that point were left without a chair.
