>Pointing out research, or writing, or anything else, ignores the reality that if the production cost warrants a sale price of $x, charging $x * 5 or in some cases $x * 100 and using legal protections to do so is inherently greedy and immoral.

Why is, for example, a student discount, "inherently greedy and immoral"? I don't see why there's intrinsically any moral element to charging groups differently based on their willingness or ability to pay.

That's fine? $200 (a figure I saw quoted somewhere for a single college coursebook) is more than the annual fees for some government-run colleges here (in India.)

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

Creating fair markets should be the #1 goal of capitalism.

>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.
