It's easy to complain about how expensive things are when you live in the United States. In reality, many things are way more expensive in foreign countries!
The average price of gas in the US is just over $2 a gallon, which is actually pretty cheap. Just be lucky you don't live in Europe or Hong Kong where the prices are often over $7 a gallon, even with the recent price lowering. The current highest price for gas in the world can be found in Norway at $7.25 a gallon.
