Businesses sustain businesses, because businesses are linked together in so many different ways. For example, if you start a internet business, which sells books, then you need a lot of other businesses. First, you will have to get a server. So companies that have servers will benefit. Internet companies will also benefit, because you will be using their services. Google will love it as well, since you might user their search advertising. Also keep in mind the deliver companies, postal services and credit card businesses that will benefit. In the end, this one business sustains other businesses.
