In this article, I understand that Free price system is a solution to the issue of offer and demand. While it might be true in most cases, is there cases where it is not true?

For instance, what does happen when a vital resource (such as food or appartment) is not available for everybody because too much expensive? What does happen if a private company is in position of cartel? What does happen if price of energy or foreign money is instable? Why does popular china maintain fixed prices on some products? 87.89.44.229 (talk) 23:20, 11 January 2011 (UTC)[reply]
