The reason Ford, or any other automaker for that matter, doesn't increase the production numbers is a simple business philosophy- supply and demand. That rule says that if the demand is high and supply is low, the PRICE can be HIGHER. Sure it would be easy to increase production to try to meet demand, but the price will come down. Think about how the first releases of a high demand new model command premiums over MSRP, but after the model has been produced in a greater quantity dealers begin to discount and the automakers add rebates (see "PT Cruiser"). It's not always as simple as increasing the supply to improve profitability.
