I don't believe that administrations can control the price of gasoline, but the oil companies can and, I believe, do. They tell us every year that the price of gas goes up in the summer because the demand goes up and, somehow, summer after summer, they're taken by surprise and just don't have enough supply. It's the darndest thing. Seriously though, an oil company's primary responsibility isn't getting fuel to its customers at a fare price. Providing energy is just a means to an end. The primary responsibility of a publically held companies is to make money for its stockholders. If you want a true market economy you just have to learn to deal with it.
Macy's can control the price it sets for gold chains. But, it cannot set the world price of gold.
