Creating value isn't necessary or sufficient for capturing revenue streams. When a new technology is invented, for example, there are usually many people involved: there is basic science and mathematics research laying the groundwork, applied research, manufacturing, commercialization, design, marketing, etc. Typically the revenues do not go to these players proportionally to their contribution. For example, a scientific breakthrough may produce considerable value, but it is not typically possible for the scientist(s) making the breakthrough to personally capture the value, because one cannot own scientific breakthroughs. Instead, the value accrues to society generally, including people who did not create it—it might form a major contribution to an upcoming product of mine, for example. If the product is successful, I'll gain wealth, but the scientist whose work enabled the product won't. (Patents are an attempt to provide an accounting mechanism for owning at least those kinds of breakthroughs classed as "inventions", but have their own set of problems, and at least in principle don't apply to basic math/science discoveries anyway.) And some people simply make money by capturing economic rent.
