„It is well documented that economic prosperity tends to persist across generations. Children born to parents with high levels of education or income can expect to do better than children born into less favorable conditions. These differences can be attributed in part to the fact that children are born with different cognitive and non-cognitive capacities to acquire the knowledge, skills and attitudes—the human capital—that the labor market values. The genes that are passed on from parent to child may limit the potential of an individual to achieve in the labor market, while the environment that person grows up in influences the extent to which that potential is reached.“
