rich, dumb, and lazy vs. poor, smart, and industrious

"The study found that family background exerts a stronger influence on a person’s income than even his education level. And its most striking finding revealed that you are more likely to make your way into the highest-earning one-fifth of the population if you were born into the top fifth and did not attain a college degree than if you were born into the bottom fifth and did. In other words, if you regard a college degree as a rough proxy for intelligence or hard work, then you are economically better off to be born rich, dumb, and lazy than poor, smart, and industrious."
