Answer:
The U.S. is a market oriented economy with moderate taxation and regulations.
The measures that the U.S. government has taken to create economic growth, stability, full employment, freedom, security, equity and efficiency are mostly market oriented: lower taxes for corporations and some individuals, less regulations, the signing of free trade agreements, the promotion of applied research with universities in alliances with the private sector, and so on.
These policies have been largely succesful. Gross domestic product has continued to grow at a steady pace ever since the 2007-2008 financial crisis was overcome. Inflation has been in the target that is set by the Federal Reserve, and as for GDP Per Capita, the U.S. has one of the highest GDP Per Capita in the world, with $62,000 USD per person in 2019.
