Having multiple streams of income isn't unheard of today. This is actually something that's been prevalent in the business world for many years. But people don't see the business aspects of their own lives. There can often be a lot of correlation.
For those who do decide to start a business, just because you start one business doesn't mean you can't start another. Did you know that one business entity could be an owner of another? Yet, it depends on the type of business structures you have in place. People hear about these things with publicly traded companies, but it can be done with closely held (private) businesses too. That means that even if you're starting small today, you too could very well build your own business empire.
