Who holds the power of capitalism?

In a capitalist system, the means of production are privately owned and operated. Over time, this results in resources being controlled mainly by large corporations and conglomerates. Capitalism is driven by profit motive, so in a capitalist system, the allocation of resources is decided based on making money according to supply and demand.

In a socialist based economy, the means of production are publicly-owned, meaning resources would be allocated according to the needs of the people by a governing body.
