The history of relations between the American state and with the market, with free enterprise, is unique. In America, formed in his own ideal conditions for the formation and development of capitalism, for a state that grows and increasingly controversial with roots in the economic life of economic principles. In other words, the state and market in the United States were gaining strength at the same time, although economic function of government to the greatest extent manifested in 19^th century.

In a market environment, the efficiency criterion is the profitability of any business. In some cases, it is impossible to talk about efficiency, as measured by profit. It is, for example, in such important areas of modern society such as education, the fundamental
science, and environmental protection. Here is role of the state is more complicated. On the one hand, the state is a kind of guarantor of the market system, or it can not support those areas of society, where market incentives "stalled." This implies that the state nature of their economic activity becomes both a constituent element of a market the device, and a stabilizing factor society as a whole. And here we must once again focus on the so-called "Intervention" of the state into a market economy. Indeed, if State seeks to replace or even to a certain extent replaced by market and competition, here there is a real intervention. But when state acts as a guarantor of the rules of the game, the guarantor of market and competition, in this part of it fits in the market principles behavior.
