Both capitalism and communism are economic systems that focus on production and ownership of goods. They differ primarily in who owns and controls production - in capitalism it is private individuals and companies, while in communism most major production is owned and controlled by the state. Both systems also rely on the accumulation of capital/wealth, though how it is distributed differs between the two philosophies. Lastly, both aim to structure and develop an economy, though they take opposing views on private property and class structures.
