Some critics say the money was spent on rebuilding militaries and warring. Others say the money saved Europe from being made into communist countries. If you asked the Europeans who benefited from the money they would tell you the money rebuilt their nations and economies. I vote for the latter after seeing how well Europe did recover and have stabilized the peaceful and democratic nations of Europe
The US has already developed. Many of the emerging former Communist Bloc nations of Eastern Europe could be considered developing.
to help rebuild Europe
The countries of Eastern Europe (which became satellites of the USSR after World War 2) in most cases did not accept aid under the Marshall Plan because of their control by Moscow.
Eastern Europe is a region in Europe composing of many nations. No country produced Eastern Europe.
Generally speaking, the non-communist nations of Western Europe were doing well in comparison to nations where Stalin had established communist governments in much of Eastern Europe. The free market policies of the West were yielding better economic growth then the centrally planned economies of Eastern Europe. The US helped to jump start the economies of Western Europe through the Marshall Plan.
The Soviet Union wanted control of eastern Europe. The United States wanted independent nations in eastern Europe
The Eastern European Nations were controlled by the Soviet Union, a communist government, and they did not have self-rule nor could they have free trade with the rest of the world as the Western European nations did. The USSR also refused help from the democratic western nations so they did not have all that help to fix up and grow the economies of the Eastern Nations.

The Marshall plan
NATO- the North Atlantic Treaty Organisation offered all European countries economic and military aid. While the Marshall plan offered only economic aid. But both were attempts to stop communism from spreading and causing the "domino affect"- which Eastern politicians believed at this time would happen (and they were right.)
The Soviet leaders probably viewed the Marshall Plan and NATO as direct threats to Soviet security. Soviet leaders felt the United States was using its wealth to buy influence and power in Europe. They feared that strong, rebuilt Western European nations would be a threat to its satellite nations in Eastern Europe.
The economic and technical assistance offered by the Marsall Plan was not accepted by the Soviets and it's satellites in Eastern Europe.
