Western Europe is more developed than Eastern Europe because the market economy of Western Europe provides an economic advantage

Explanation:

Stark differences persist between the western and eastern part of Europe. While western Europe was under the influence of Capitalism mode of production (led by the US and Great Britain), the eastern part was led by the erstwhile USSR following socialist mode of production.

Under the market economy, open competition and adaptive hand-holding by the US, western European countries prospered by leaps and bound. Marshall plan prepared by the US helped in post-war reconstruction of western Europe. On the other hand, eastern countries fell prey to the despotic rule of dictators, political instability and socialisation of assets. There were no such private assets and the important assets were nationalised. In the long run, the socialistic model of the market could not stand up to capitalism and fell in 1991 when the USSR disintegrated.
