Children who are inattentive in kindergarten are more likely to report lower incomes than their peers at the age of 33 to 35 years of age, a study has found. On the other hand, the most “pro-social” boys – who help others, are considerate and willing to participate in educational projects – are overwhelmingly headed for careers that pay more than the average, according to researchers. “Over a 25-year career, the differences between the two groups can reach USD 77,000,” researchers.

Problems of inattention more often lead to kids dropping out of school or having trouble adjusting as they enter the labour market. On the other hand, the researchers found, “prosocial” children are on a trajectory that leads to better-paying jobs.

Differences were evident when data was crunched for in 2015, a year when the grow-ups were in the prime of their working lives and when the wage gaps between individuals were stark. The researchers said that childhood inattention is associated with a wide range of long-term adverse outcomes, including lower earnings over the course of a career. The researchers also found that women earn only 70 per cent of what men earn.
