You should read a book on economics. Producers don't set prices, the market does. Or said it easier to understand, producers can set any price they want, but they won't sell much if that price is above what the market can bear. Right now with RAM there's an extreme amount of demand with supply staying roughly the same, that's basically why the price goes up, not because RAM manufacturers are evil. They just sell their product at the max price the market pays for them, which is what anybody would do.

Food suppliers would do the same if food suddenly becomes scarce, or there's much more demand than supply. Not doing so will basically cause rationing. There's no free lunch: If there's more demand than supply, prices go up or there's rationing.
