If someone is going out of their way to hide their wealth. They are likely not going to brag or own any showy objects. There are 3 ways to find them out: 1 - Strong finance and legal knowledge. If someone knows a lot about money they likely have a lot. 2 - Check their credit card. A persons credit card can give away their credit rating and typical monthly spend. 3 - Wealthy people realize their time is worth a lot. You may notice them out-sourcing some expensive tasks like lawn maintenance.
