Explanation:

Socialism, communism, and capitalism are economic and political theories.

They developed mainly in the 18th and 19th centuries as responses to the changes brought by the Industrial Revolution, not specifically to the Great Depression, nor are they ancient Greek/Roman philosophies or just about organizing industry and trade.
