Over the past 70 years, international trade has become freer.
Trade barriers have been broken.
Quotas removed.
Subsidies eliminated.
Tariffs toppled.
More countries buying and selling goods and services with other countries than ever before.
And while some trade barriers still exist and new ones occasionally pop up, many countries, leaders and diplomats are chipping away at them, trying to unleash free market forces and the benefits and costs that come with them.
