Let me explain. At its core, the economic system we have here in the United States is based on two basic things: 1) the right of any person or group of people to run and operate a business and 2) the right of any person or group of people to buy goods or services from the business of their choice.
This system is called the free enterprise system and is designed to give people the broadest choice of goods and services possible and reward those people (we call them entrepreneurs) who provide the best goods and services.
If you ask someone like Rand Paul, he'd say somebody participating in this sort of system is a "capitalist." But the cleanest definition of a capitalist is someone who uses their money – their capital – to make more money. Some capitalists do this by investing their capital in the stock market; others do it by investing in other people's start-up businesses: they are called venture capitalists.
These kinds of capitalists do play their part in our society. Sometimes, they help small businesses get off their feet. But here's what you won't hear on Fox Business or CNBC: capitalists aren't that productive and they aren't actually necessary. Many are just like Paris Hilton: they sit around on their butts by the pool all day waiting for their dividend checks to come in. They make money while contributing absolutely nothing to the rest of society.
And here's the thing: free enterprise works just as well without capitalists, capitalism, or even venture capitalists. Worker-owned cooperatives are just as successful as any business backed by a massive Wall Street loan. The Mondragon Cooperative in Spain, for example, employs more than 90,000 people, includes more than 250 companies, and generates a yearly revenue of around $25 billion. There are NO capitalists involved; it's entirely owned by its workers.
