What is the difference between communism, socialism, and capitalism?

[GeniusScot]

Communism is the believe that all business, should be ran by the state under a dictatorship of the proletariat. It comes from the ideas of Marx & Engels. Eventually, the dictatorship is meant to dissolve and people are meant to live in a classless society based on co-operation. However, most dictators aren't too keen to give up their positions of power. Examples are Cuba, North Korea & The Former Soviet Union.

Socialism is a vast political ideology. It's pretty hard to give a definition as it covers so many systems - Anarcho-Syndacilism, Anarcho-Communism, Marxism, Social Democracies, Maoism, etc.
The most common form of socialism in Europe would be a social democracy which retains democracy and the capitalist mode of production but some things like Healthcare & Education are ran by the government because socialists believe that these things are not to be trusted with the private sector as they only want to make a profit. Social Democracies tend to put an emphasis on worker's rights and equality. Examples are Sweden, The Labour Party in the UK pre-1999 and organisations like the NHS.

Capitalism is the believe that the government should run nothing and it should be trusted with the private sector. This can lead to inequality& poverty. Examples would be the Republican Party, Tea Party, etc.
