If my startup was selling a product which was so successful I couldn't afford that product myself, it would be a good problem to have. I don't understand this article. Either Bolivian farmers want to sell their products for the best price they can get (in which case more power to them) or they want to subsidise their neighbours' quinoa-based diet. This is a simple question of utility. And I can't blame them for choosing to bring more net value into their country by exporting a prized foodstuff to richer countries. I'm sure the USA would be happy to trade them comparatively low-value corn or wheat to quinoa. Am I missing something?
