>If the market is fair but the price is wrong, the price will change.

You're assuming that a price that no-one in a developing country can afford is the same as a price that is "wrong". It's perfectly possible that a price that no-one in a developing country can afford is "right" from an economic perspective in that it's profit maximizing for the producer.

If you have to sell your product at the "right" price, meaning profit, in a market that can't afford that price then the problem isn't the price; you are selling the "wrong" product.
