technically you are right, however these companies function on a daily profit type thing, so theoretically it would work. but, it has been tried before with supreme failure. obviously, the only thing americans can band together for is .39 cheeseburger day at mcdonalds. on another note, it would work even better if we just boycotted one manufacturer for say.... 3+ days. then there gas prices would plummet and the others would have to follow suit in order to keep themselves in business. but hey, just keep in mind, that our gas prices are still much cheaper than 98% of the rest of the world
