What is capitalism?

Capitalism is an ecomomic system based on private ownership and on the investment of money in business ventures in order to make a profit.

The earliest form of capitalism originated in Rome,Middle East and early Middle Ages. But capitalism as a practice is characterized by the following:
The accumulation of means of production(material, land, tools) as property into a few hands; this accumulated property is call "capital''and the property-owners of these means of production are called ''capitalist''. The means of production and labor is manipulated by the capitalist racional calculation in order to realize a profit. So that capitalism as an economic activity is fundamentally teleological.
