There is no fundamental difference between socialism and communism. One says you get what you need, one says you get something based on what you contribute but need and contribute are not defined by the person they are defined by some external group based on nothing other than their feelings. It's just word games masking the underlying reality that one group is butt hurt about what some other group was able to get for their input and the first group wants to confiscate that output for themselves. Both groups concentrate power in government, both groups are very susceptible to being taken over by a strong man dictator, both don't end in utopia, they end in suffering under some dictator. Socialists are just communists trying to soften the language around what they are butt hurt about to make it more palatable in the hopes enough people fall for that stupidity that they can implement their confiscation plan to reach their utopia (which never, ever happens. It devolves into dictatorship and suffering or is in the process of doing that). Fascists are just another brand of utopian dictator that ends in suffering (their rhetoric seems to be built around disgust rather than envy but other than that it's a train to the same gulag).
