Describe the concept of global economy.

The ideology of a global economy revolves around the spread of capitalist economic system around the world which would have minimal influence by the governments of the world. The concept surpasses national boundaries and advocates to make the world almost a single economy where multinational companies can do business without restrictions from different governments. I personally do not agree to a 100% implementation of this concept as the results of it could mean the hold of a few business persons or groups on the whole world which could lead to wealth maximization for only these few.
