While the economic and industrial collapse of the capitalist countries broke levels never before seen, the Soviet economic strength reached remarkable achievements.The planning and socialization of the economy, together with a considerable isolation at the international level of the country, avoided the nation's own evils of crises such as unemployment, falling prices and overproduction. During the years that coincide with the Great Depression in the West, the Union increased its capital investments and managed to multiply its production and working population. Thus, its annual growth was around 13-14%, tripling and quadrupling the growth that the United States and Western Europe had achieved in the years of prosperity of the 1920s.
