A little dig through the archives might show the AP what happened the last time government decided they wanted to lower gas prices.
Government do-gooders can t just sit idly by and let people pay exorbitant prices for potatoes.
They decide to help. They tell potato growers they can t raise prices. The potato growers decide they aren t in business to lose money so they stop growing potatoes. Instant shortage compliments of the government. You can substitute gas or any other product in the above example.
