Is there any truth to the saying '99% of the world's millionaires have become rich by doing real estate'?
I can name far more non-real estate millionaires than those who are. That statistic isn't only not valid, it's not even close.  Update: The correct quote is "90% of all Millionaires become so through owning Real Estate" and it's attributed to Andrew Carnegie. Given that he was born in 1835, I can imagine that his statement was true at he time, but not today.
