Is Warren Buffet really frugal, are any billionaires or millionaires really frugal?

They are frugal to the amount they spend compared to the amount they earn. Think about it they live in a million dollar home they make ten million a year. Average people make 35,000 a year and live in 100,000 house. Average income household live way out of their means, why do you think we have an economical crisis.
