The best way to describe Karl Marx's theory of communism is that he aimed to redistribute wealth.

The best way in which Marxism, or Marx's theory of communism can be described would be: it attempted to gain a more equal, and more just, distribution of property, and especially of profits made out of porduction and selling, between the workers and the business owners, and also to establish an economic system where the way profits are distributed depends more on the time spent by workers on the production of goods, rather than the prices set by the business owners and that seek to give this second group the greater part of the profit.

Explanation:

Karl Marx was a German theorist, economist and philosopher, who lived between 1818-1883. Making use of the theories on capitalism, and especially the Labor Theory of Value, from Adam Smith and David Ricardo, and in conjunction with his best friend Friedrich Engels, Marx used that Labor Theory and with other influences, created with Engels what today is known as the Communist Manifesto, which was published in 1848. It is in this Manifesto that Marx and Engels lay de groundwork for what later became the communist and socialist movements. Basically, Marx established a huge division between the Proletariat (working class) and the capitalists, and he also established that redistribution of profits and gains had to be done between these two groups, in favor of the laborers, who were the ones who put in labor power in order to produce and thus make profit.
