Why did western European economies grow faster the Eastern European economies after World War 2?

Western European economies grew faster than Eastern European economies after World War II due to several factors, including the implementation of the Marshall Plan, which provided substantial financial aid for reconstruction in the West. Additionally, Western Europe benefited from market-oriented reforms and integration into the global economy, fostering innovation and trade. In contrast, Eastern Europe was constrained by centrally planned economies that stifled entrepreneurship and efficiency, coupled with political instability and the burden of Soviet influence, which hindered economic growth.
