Billionaires

Rihanna is known worldwide for her music career, but she has also made a significant impact in the financial world.

You might think that the world's billionaires would know it all when it comes to money, finance, and investing, but Jim Cramer thinks otherwise.

Billionaires have more money than they could ever need. They hold the rare power to change our world. What, then, do they do with all of that wealth?

No billionaires. No extreme wealth gaps. Just a hard cap—once someone hits $1 billion, everything above gets taken and redistributed. It sounds like the kind of idea that could fix a lot of problems overnight. After all, $1 billion is more money than most people could spend in a lifetime.

In 2006, billionaire Ingvar Kamprad revealed that he stayed rich by driving an old, used car and collecting salt and pepper packets from restaurants.
