Final answer:
Both the USMCA and the European Union work to facilitate trade among member countries through reduced tariffs and the removal of other trade barriers. The EU has also aimed for deeper economic and political integration including a common currency, while the USMCA focuses solely on trade.
Step-by-step explanation:
The USMCA and the European Union (EU) both aim to facilitate trade among member countries through the reduction of tariffs and other trade barriers. This is similar to how the EU began, evolving from a free trade association to a common market, and eventually to a union focused on economic integration with the introduction of a common currency, the euro, and the removal of internal obstacles for the movement of goods, labor, and capital. One significant difference, however, is that while the EU has indeed moved closer to political union, no such significant efforts towards political integration exist within USMCA. Additionally, it should be noted that the EU has undergone changes in size with Brexit, where Britain exited the EU, but there is no indication that the USMCA has decreased in size.
