Communists believed that wealth should be owned by the state.
Explanation:
During the Cold War period, the communism spread out around the world. Many countries from multiple continents found the communism very appealing, and with the support of the Soviet Union they managed to fend off the Western countries in their attempt to stop this process. Most of the countries that adopted the communism did so through revolution and military conflict. Such countries were:
Vietnam
North Korea
Cuba
Venezuela
Cambodia
One of the main things in which the people that adopted the communism believed was that the wealth should be owned by the state. This was due to the goal of making everyone equal, including by wealth, and that by controlling all of the economy the government will be able to do so. Unfortunately for the people though, this didn't turned out as they hoped and believed it will, but instead resulted in few people controlling almost all of the wealth, while all the others lived in poor conditions, often struggling to survive.

The knights and the samurai shared lot of similarities in their social status and their purpose in the societies. Both of the were protectors of the leader of the country. For their services of protection they were given free pieces of large parcels of land. They were the best warriors in their respective societies, and when there was a battle they were the elite unit that usually was the one that was winning the battle/war. Their only job in the society was to train for battle, and fight in battle.
