What is the fundamental reason why the United States put forward the Marshall Plan?

The official name of Marshall Plan is "European Recovery Plan", which, as its name implies, is to provide economic assistance to European countries that suffered heavy losses in World War II to help them rebuild after the war. In addition, it naturally has the purpose of preventing the Soviet Union from expanding its power in Europe, which is obvious.

When the Marshall Plan was put forward, the Soviet Union was invited to participate in it. The United States promised huge aid to the Soviet Union, but the condition was that the Soviet Union was brought into the European integrated economic system, which undoubtedly ran counter to the highly centralized economic system of the Soviet Union. In fact, the United States is just posing, and it doesn't really want to include the Soviet Union in the plan. Instead, it relied on the Marshall Plan to drive Soviet troops out of Europe.

Marshall Plan was implemented as scheduled from 1947 to 1952. In just over four years, the economies of all participating European countries (except Germany) recovered to the pre-war level, which greatly promoted the economic revival of Europe. The political influence is even worse. Marshall Plan consolidated the rule of capitalist political parties in European countries, weakened the power of communist political parties in various countries, significantly promoted the process of European integration and consolidated the alliance between western European countries and the United States. These are naturally strategic meanings that have been considered before the implementation of the plan.

In fact, the Soviet Union has a similar plan in Eastern European countries, called the Economic Mutual Assistance Committee (сэв), but it is not as "generous" as the Americans, and it only "plunders" industrial raw materials from satellite countries, so the impact is far less than the Marshall Plan.
