We will be seeing that shortly, in the global arena. Modern agriculture is getting better and better at getting more crops out of a given acre of land. Unfortunately, it takes money: money for fertilizer, money for herbicides/insecticides, money for machinery and fuel. You get to the point where the productivity of some of the population is not enough to get paid enough to buy food. And the willingness of the Western middle class to impoverish ourselves in order the feed the world is lessening.
“We will be seeing that shortly, in the global arena.”
I think you are right. Not only costs, but we may see loss of confidence in currency, massive economic slowdown, solar activity is about to go into a minimum, weather seems to be getting more aggressively destructive, and all of it is happening just as r-numbers and K-disatisfaction are both peaking. It just seems like multiple ways for things to go bad, and one way for a perfect storm of sorts.
I can’t point to a specific piece of evidence, but it does have the feel of a perfect storm of some sort.
