I was making a general statement about when anime has a political theme, not on that particular anime. Though I guess you could find a utopian vision in a nation that views all to be equally worthless and champions genocide and calling the dark young of shub niggurath to stomp on people.
Somethin to keep in mind is that it’s a labor intensive harvest and the products aren’t really what we’d want to market. You’d wait until the whole lot of them kind of dies down and harvest winter squash, dry beans, and flint corn then till the remainder back into the soil.
It’s not bad for substinence farming, but you’re not going to get the yields or reasonable market prices with those crops.
