Good news for parents who think their rugrat is a little on the disobedient side — a new study suggests that nice kids finish last.
Researchers tracked more than 700 children in Luxembourg from the age of 12 to 52 and found that those who were more defiant than their well-behaved peers as kids made more money in their later years as adults.
Floating a few theories, researchers say they might be more aggressive when negotiating salaries or raises. They may also thrive more on competition and be more willing to bend the rules to their advantage.
This study falls in line with other research that suggests disobedient children are more likely to become entrepreneurs as grownups.
And if you needed any more convincing, look no further than the richest man in the world, Bill Gates. He might seem pretty straightlaced, but remember, he was busted for speeding and driving without a license at 19.
