Why America has the best economy

You can not objectively say America has the best economy, because that is an opinion. But I can tell you some positive things about our economy, in America we practice capitalism and have a market economy. This allows citizens and consumers to have more control of the market. It also encourages competition between businesses which causes lower prices and reduces production of products low in demand reducing waste.

It can provide a social code to protect each citizen's future economical earnings. and then obviously defending the country from invading countries.
