Does wearing of expensive cloths, shoes and other expensive things a sign of being poor? Or does it mean the rich doesn't wear expensive things or doesn't leave a luxurious lifestyle?
This happens very often, rich people want to appear simple and poor people want to appear rich. However, not all are like that, so we can't generalize that all poor people look luxurious, maybe because of the demands of their jobs such as celebrities, lawyers and maybe there are other jobs that require them to look glamorous to attract fans or clients.
Rich people do on average want to appear simple, don't want to be complicated. They always buy everything in cash, never on credit. They have businesses, savings, and investments everywhere. The point is rich people are more secretive about their personal wealth, and they will give alms without other people knowing. This is very different from people who want to look rich and show off what they have.
