The free market economy is no doubt the primary stimulus that has led to the United States' dominance in the world economic community. By naturally rewarding those producers that excel, excellence is actively encouraged and those that inefficiently produce goods or services not valued are eliminated. Thus, the economy becomes a self-sustaining and self-maintaining machine, consistently and constantly achieving the best possible result. The free market economy is entirely based on the principle of supply and demand. Under this concept, consumers decide for themselves which companies will stay in business, voting with their dollars by spending on those businesses they consider most worthy. By doing so, those companies that are best liked, or most in demand, are granted the privilege of supplying the goods and services that consumers pay for. In that sense, efficiency is achieved. Those companies that best perform to the expectations of consumers are left prosperous in the market, while their less efficient counterparts simply die out of the market, starved of the dollars of consumers who simply prefer not to buy their products. With such a system in place, American businesses are literally forced to be efficient to the highest degree. As a rule, what's efficient in one place will be efficient in most other places, thus American businesses are fierce competitors no matter where they choose to sell their product, having been formed in a competitive environment that breeds optimality. When the opposition is made up of businesses overly protected or directed by their respective governments, the tough American businesses usually make short work of them. It has been proven that the free market system more efficiently allocates capital and resources than any central planner could, and America has seized on that concept. With such an edge at a basic level, it's no wonder that the United States is on top of the financial world. The cycle is a self-perpetuating one. As more money is pumped into the system by efficient businesses, more leverage is attained, allowing America to dictate the rules of the game, to its own advantage, of course. Other countries are beginning to adopt the competitive nature of the American economic system, producing companies that are giving their American counterparts a good run for their money. It can be arguably stated that within a few decades, the United States will have to deal with competition just as well equipped as its own. For the time being, however, the game is stacked in favor of America.
