Ok so is this story, I think it’s from the book Freakonomics, but I can’t remember. So I’m paraphrasing:

Monsanto (or similar) goes to like Vietnam or Cambodia (or whatever).

They say, use our GMO rice, it will double your yield per year.

They say, great!

A year later Monsanto comes back, and finds the Vietnamese have only planted half their fields.

“Why did you only plant half the field?”

“Because with your seeds, we can work half as much”.

I tried half assedly find the original story but the other cheek couldn’t be arsed.
