I don’t think you can tell without looking into their finances. For some, a big house and a couple of new cars signal wealth, but to me, they’re more likely signs of debt and poor financial judgment.

Personally, I live in a small, 75-year-old house, drive a 17-year-old pickup truck, and walk around in old clothes that were never in fashion to begin with. Yet I know for certain that my financial situation is far better than that of the average person in my country. You’d never be able to gauge my true wealth from my appearance or spending habits.
