Free trade increases prosperity for Americans—and the citizens of all participating nations—by allowing consumers to buy more, better-quality products at lower costs. It drives economic growth, enhanced efficiency, increased innovation, and the greater fairness that accompanies a rules-based system.
Explanation:
Free trade is a trade policy that does not restrict imports or exports. It can also be understood as the free market idea applied to international trade. In government, free trade is predominantly advocated by political parties that hold liberal economic positions while economically left-wing and nationalist political parties generally support protectionism, the opposite of free trade.
