Mark Zuckerberg
This Harvard dropout became one of the richest men in the world. Zuckerberg has a net worth of about $80 billion so he has more money than he knows what to do with. Most of his big purchases involve real estate or additions to his Meta empire. But Zuckerberg and his wife, Priscilla Chan, live simple lives.

We all know that he dresses the same way every day. He doesn’t blow cash on indulgent purchases because they don’t interest him. Occasionally, he pays for quality when he pursues a new interest. He began training in MMA as a hobby and spent a lot on coaching but he usually doesn’t splash the cash (via Guest of a Guest).
