Dumb headline, obviously wrong. It may be true for those billionaires but there are many millionaires for which this isn't true. I know single-digit millionaires who ran away from home as teenagers and never had anything to do with their parents again.
Approximately a billion.
The big thing here isn't that they get loans. It's that they can keep taking risks, knowing they'll be OK if they fail.
I can't remember the exact quote, but essentially middle class people have one big shot they can afford to fail at. The children of the wealthy can keep taking them.
"Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000). However, this is not common anymore, and the word has been used to mean one thousand million (1,000,000,000) for several decades."
trillion = million x million x million [tri]
This is still the case in Dutch for instance, where 1e9 is a "miljard".
Corollary: If you can count your money, then you're not rich. (Liquid net worth is always an educated guess, varies by kinds of assets and debts, liquidation timeframe, and varies by the day.)
The term "with money" is subjective and open to interpretation, but I don't think that it means "middle-class" either.
Due to inflation, the term "millionaire" today does not convey the same meaning that it did a few years ago. Middle class families with high 5-/low six-digit incomes can aspire to become millionaires by passively saving their salary.
This is definitely what "millionaire" means.
