When a disaster hits an area, the cost of everything seems to go up immediately: Food, water, housing,gas and so forth. Using the laws of supply and demand, why might this be a good thing?

For a store owner maybe but hes taking an unethical advantage of a disaster when people actually need the help most as they are in dire needs. To keep the prices the same or maybe a little higher to cover his expenses of getting emergency supplies but to charge sky high prices to these people is terribly wrong, and one day he may be in their shoes as what goes around,really does come around. People reallly do need to learn sympathy and how to help other the best they can in time of need as the Bible says
