Here's a chart of inflation adjusted gas prices going back to 1918. It shows the price of gas today is actually cheaper than in 1918 after inflation is factored out. It's also below the average price of all the years since then. So it's OK. Even better since back in 1918 we spent a lot more of our incomes on other things like food and gas money was harder to come by.
Some people think prices rise or fall because something happened to cause it. In looking at the chart, however, we can see the price of gas was already too cheap by historical numbers and was pumped for a spike.
Should the price of gas rise to the upper bands, one could then make a prediction that the price was likely to fall and be right more often than not.
