Final answer:
During economic crises, both Russia and the U.S. resorted to government economic intervention with planned aspects, such as Russia's NEP in 1921 and the U.S.'s War Production Board during WWII.
Step-by-step explanation:
One way in which government economic intervention in Russia is similar to that in the United States after 1900 is the use of state control during times of economic crisis to direct labor and resources. In Russia, after the economic crisis post World War I and the civil war, Lenin introduced the New Economic Policy (NEP) in 1921, which while retaining government control, incorporated elements of capitalism such as allowing peasants to sell produce on the market and enabling small businesses to operate privately.
Conversely, the United States during World War II saw the War Production Board exercising economic planning to increase military production, a move that, while maintaining a predominantly private enterprise economy, also echoed aspects of a planned economy.
