Is an enterprise social if it produces some sort of social benefit? If so, in that sense, many or indeed most traditional businesses for profit can be considered social enterprises. Business enterprises typically produce something of value for clients and customers, otherwise they would cease to exist as business enterprises. Earning thousands or millions of customers can by definition be considered social benefit. Social refers to groups of people, as contrasted with one person. If a company produces a product or service, it has to benefit a group of people sufficiently for them to use that product or service. Owners and stockholders benefit from financial profits gained by the enterprise. Stockholders range from individuals owning relatively large percentages of a company to ordinary pensioners relying on income from micro-investments into the company. Profits from almost any large public corporation are shared among wealthy individual stakeholders to humble, modest households who have holdings in the company through an array of mutual funds managed by government-regulated financial managers.
