Your post is endemic of something I see a lot on HN. You know nothing about agriculture, but you see a minor set of stories and you think you're a fucking expert.

You have no idea if the diversified strategy has a higher expected value, or if it's just a variance play based on heat, or if different weather conditions could've affected interplay in a different way. You have no idea what the crop insurances for different crops cost. You have no idea what the weather forecasts were.

You literally know absolutely nothing about the matter.

All you know is that you've got an ideology and that you see absolutely everything through the ideas of your ideology, selectively perceiving, remembering and interpreting events to confirm and reconfirm your ideology. And you're sufficiently arrogant that you think you can glance at a farm and know what tradeoffs they considered when they were planting their fields.

And that doesn't even get into the fact that if you travel via air around the globe, nearly all of the airlines are absolutely terrible, not just the subsidized ones in the US. Thus, it's fairly clear that while you'd like to pretend that your religion explains everything, it really doesn't.
