There has been talk in the news about gas stations "price gouging." At the same time there has been talk about gasoline shortages. This is talk from people who are economically illiterate.
When an item is in short supply, prices rise until enough people decide they no longer want to buy it at that price. If the government prohibits sellers from raising prices, then we wind up with shortages, preventing people who really need the gasoline from buying it, and forcing people to waste huge amounts of time waiting in lines at gas stations.
At this time we need to let gas stations charge as much as they want. Maybe $7/gallon gas over Labor Day weekend will discourage some people from driving to the beach, allowing time for the supply situation to be rectified.
I personally am disgusted that people are so concerned that it costs more money drive to the beach this weekend while thousands of people are trapped in New Orleans without food and water.
