What is meaning of corporate world?

In a capitalistic country, such as the US, a corporation is seen and treated as an individual. This means a corporation has certain laws, ethics, etc that apply to it. The simple definition of a corporate world is the place where business ethics and laws apply and must be followed, with certain other specific behaviors that must be met in order to get ahead in such a world. It is labeled as a 'corporate world' because it is very different from the 'real world'.
