What has been the greatest advantage of creating groups like the EEC, EU, and NAFTA?
The greatest advantage of creating groups like the EEC, EU, and NAFTA is that countries can form trade regions or trade "blocks" that benefit their economic interests. These trade agreements allow their members to freely trade with no or minimum tax barriers, benefiting their exportations and importations rate.
Let's put the example of NAFTA.
On December 17, 1992, Presidents of Mexico, the United States, and Canada signed NAFTA. They were Carlos Salinas, George H. W. Bush, and Brian Mulroney. This would be the largest free trade area in the world. The entering President, Bill Clinton, supported NAFTA principles but wanted the addition of some clauses on environment protection and better labor agreements. According to President Clinton, a result of the North America Free Agreement (NAFTA) would be increased jobs and lower prices.
NAFTA has been recently renegotiated by the three countries and the new agreement is called USMCA, United States, Mexico, and Canada Agreement.

Gorbachev's best statement about perestroika is that without a perestroika, the cold war would simply not be complete. But the world could not  continues to evolve, as it was, with a sharp threat of a nuclear war.
In order to reform the relaxed Soviet Union, the democratization of the Communist Party was promoted through the policy of Mikhail Gorbachev's party "perestroika" and "glasnost". Perestroika refers to the reconstruction of the political and economic system founded by the Communist Party.
Prestroika means reformation, and volume means openness. The openness is primarily reflected in relations with the West, which gave a major contribution to the end of the Cold War.

The accomplishments of worker's organizations incorporate reasonable compensation, more secure working conditions, employer stability, and age limits for laborers.
