why is a market or mixed economy is the best match for the United States.

The basic idea of the mixed economy is that the means of production are mainly under private ownership; that markets remain the dominant form of economic coordination; and that profit-seeking enterprises and the accumulation of capital remain the fundamental driving force behind economic activity. Governments in mixed economies often provide environmental protection, maintenance of employment standards, a standardized welfare system, and maintenance of competition. Also because our economic system is capitalism.

So just put all those together. Government limited control, we have capitalist economic system & that s why it s best match for the U. S.
