Answer:
One denys, one embraces
Explanation:
Socialism and Communism believe in eqaulity - at the expense of everyone. Communism and Socialism strip people of their basic freedoms, destroy their economy and free market, trade becomes limited, and different things like that. Communism and Socialism always try, and succeed (like Hitler, Stalin, etc), of suppressing conflicting viewpoints, having an expressed opinion on social, political, and/or religious matters, and they will always make the Government the regulating factor on how much you make, the food you can buy, and how much resources you and/or family could have.
Effects of Communism and Socialism: destruction of free enterprise, basic freedoms stripped away, censorship and propagranda on mass displays, gulags, and (mainly) pushing for a massive government overtake. Examples of Communsim destroying the lives of many would be China, Cuba, Russia, and Germany. That was saw mainly when all the conflict began for power, like all the mini wars and then WWI and WWII.
Capitalism is different because it allows for the marketplace of ideas to exist, it allows for the average person (or experienced person) to get a job that he/she could realistically get based upon the skills they have, plus, Capitalism allows for the private entity to have control rather than the state or Government. Example, if you want to start your own business come to a Capitalist Country instead of a Communist Country, why? Because the mass regulation, the don'ts, and how much government intervention would kill your business and have no privacy for you nor your users. The list can go on.
Capitalism is here to serve what the general market wants, doesn't wants, and will expand upon that. It is the complete opposite when referring to Communism and Socialism. Plus, Captialism allows for the intitivate of people rather than government and Capitalism allows the favoriting of the free market.
Communism/Socialism is based upon the Government's planning and will that will have limitations on private control of resources of any kind. Always remember this, when the government is involved much is restricted and poverty rises as the human has no chocie. Whereas Capitalism allows the average human to grow, expand, and flourish in what he/she wants to do in their own life and what they want to achieve. Capitalism is for benefiting people rather than killing the dreams and lively-hood of many.
So, even in this long answer, that is the answer and I hope this helps as this is a brief (but summarizing) answer that will surely help clear things up. If anyone needs more of an answer, I am here or look up Ecomonist Miltion Freedman. Mr. Freedman is one of the greatest economists ever that explain the economy, Capitalism, etc.
