Strive for equality in the society

Explanation:

Socialism refers to an economic  model in which the production and distribution of goods and services is a shared responsibility of a group of people.

Communism is an economic system that seeks to create a classless society. It means that the major means of production,such as industries are owned and controlled by the public.

The key feature that ties both economic systems together is the fact that both of them try to eliminate societal classes, and create equality amongst all members of the society. They use the methods of "collective ownership" to achieve this.
