In communism the expected outcome is an equal wealth spread among the people. There will be no hunger, no war, and no political chaos. This is all very good. Then only problem is in practice this never happens. There is lots a famine, natural and man made, war, and tons of political chaos. People are naturally greedy and they want power and money, so they are never content with being well off. They want more. On top of that, the living quality tends to go down in communist countries compared to their capitalist counterparts. This is greatly demonstrated in east germany vs west germany. The west was capitalist and very successful economically whereas the east was communist and struggled all of the time.
