Explanation:
The ideas of the socialist party can serve as a basis for the creation of communist ideas. Since socialism is a political system that wishes to attribute social and economic equality to all citizens of a country. For this reason, socialism asserts that it is right for workers to have power over the means of production, along with employers, since it is the workers who produce everything that circulates in the country. However, socialism is less radical than communism and believes that there must be agencies elected through direct democracy, to help and organize the working class.
