If you're talking about Alexandria Ocasio-Cortez from New York's 14th District, who is a self-described "democratic socialist" ... well, it just sounds like you don't understand the 5 fundamental differences between socialism and communism. Should you care to know, here they are:
1) Socialism is just an economic system while communism is both an economic system and a political system. Socialism is commonly regarded as an economic system that seeks to achieve equality among members of society. Communism, on the other hand, is both an economic system and a political ideology that advocates a classless and stateless society and rejects religion. It is regarded as a more extreme form of socialism.
2) They also differ in the management and control of the economy. In socialism, the people themselves decide through communes or popularly elected councils on how the economy should work. This makes socialism a liberal system because the majority of the people have a say on how the economy should run. Communism, on the other hand, controls it's economy through a single authoritarian party. It is therefore characterized as conservative because the economy functions based on the decisions of a few.
3) The views of socialism and communism also differ in the distribution of wealth produced by the economy. Socialism supports the view that the goods and services produced should be dispensed based on the productivity of an individual. In contrast, communism believes that the wealth should be shared by the masses based on the needs of the individual.
4) Socialists can own personal properties while communists can not.
5) Finally, socialism and communism differ in their views on capitalism. Socialists believe that the capitalist class can be used as a good instrument as long as it is properly controlled. Communists, however, believe that capitalism must be totally destroyed in order to give way to a classless society.
