Yeah... just convinced a friend to stock up based on this.
As per your other link, grocery sales are decreasing (though you still can't get eggs, rice, flour, pasta etc.) and so I think we'll have a time when things will be more available than they are now, but then the supply chain might get hit by closed borders and so forth. Thinking forward to that, I broke isolation yesterday and went to the grocery store and spent $500 even though I could have stayed away for another few weeks.
Also am willing to spend 2X for things like flour and oatmeal if I can find them. I did notice that in general, if you want to spend a fortune on gluten-free organic products, the shelves are still mostly full! I have my limits though. I won't pay more for rolled oats than I would pay for a fine cheese (saw some at $19/pound).
I heard an interview with a farmer a couple years ago who said (roughly from memory): "Don't kid yourselves. You have a choice. Your food will be picked in the US by a Mexican or in Mexico by a Mexican. Those are your two choices. As it becomes harder for us to bring in immigrant labor, we're buying up land in Mexico and moving our farming operations there."
So even if you can bring in the labor, "high-touch" crops just aren't grown in the US much anymore.
Some people are saying it will be like when we were kids and things will only be available in season. But it won't be. I grew up with all kinds of fruit and vegetable farmers in Vermont where we would have these ridiculously short seasons for things like strawberries and asparagus.
Now, lots of those fields are growing houses and Home Depots, which are very hard to eat without lots of condiment.
