Capitalism as Economic System

Generally, Capitalism is a free market system where individuals in the system pursuit for their self-interest and the legal framework is not very regulated by the government. The market will only listen to the dollar. Capitalism promotes functional distribution as if you work hard, you will get the reward.
Islam supports the functional distribution as long as it is equitable to the community. The income and wealth should not only be concentrated in the rich people hands rather the distribution should take consideration of poor people.

Here, a short video attached regarding the history of Capitalism.
