The wealthy don't like debt
Affluent people are more likely to "avoid debt like the plague" unless it involves a business venture, Flurry says.
"People who are trying to get wealth will leverage themselves hoping for that break or thinking that eventually they'll be able to catch up," he says. "But avoiding debt is the key to becoming wealthy and staying wealthy."
Brad Klontz, a CFP professional and associate professor of personal financial planning at Kansas State University, says his research has found that the rich are often "money vigilant," which can mean they're less likely to buy on credit and more likely to pass on a purchase if they can't pay cash.
"Wealthier individuals are more anxious around making sure they have enough money and are managing it well," Klontz says.
It's important to remember that you can learn to stretch your money and accumulate wealth, regardless of your income level, by living below your means, Flurry says.
"Money doesn't really care who owns it; it will go wherever it's being attracted," he says.
