Why concede that which is not true. Making up your own definition is your definition, or de facto opinion, of what the word should mean. Monopoly refers to a sector or industry dominated by one corporation, firm or entity.
Monopolies can be considered an extreme result of free market capitalism: Absent any restriction or restraints, a single company or group an enterprise becomes big enough to own all or nearly all of the market (goods, supplies, commodities, infrastructure and assets) for a particular type of product or service.
Prove yourself by providing a definition from the glossary of a standard business text. I’m not interested in your personal definition. You have a personal axe to grind against anyone that makes make more money than is personally acceptable to you. This is the leftist attitude. I’ve heard it a thousand times.
I didn't give you a personal definition. I gave you google. I even hot linked it for you. It is you who are making up your own definition. Show me where you are quoting all that you typed. Why didn't you?
