Sobre o efeito da educação na distribuição dos rendimentos dos norte-americanos encontrei esta interessante constatação:

“There has been much more growth of inequality among college graduates than among noncollege workers,” Katz says. Only some people, he says, are coming out of college with the high-level abstract-reasoning skills that fully complement the new information technologies and command high salaries. Workers with “midlevel” skills, by contrast, are more likely to see their tasks simply replaced by computers. Does that mean, then, that too many people are going to college, and that the rewards of a B.A. are overrated, as some commentators have recently suggested? “That’s absolutely wrong,” Katz says. “The reason we know that is the following: It’s true that there’s growing inequality among college graduates. But there’s shrinking inequality among noncollege workers. The market is very bad for people with only a high-school diploma — they’re not doing much better than people who dropped out in the eighth grade. So the return [on investment] to college is still very high. Even if you wind up in the bottom half of the college group, you’re still much better off than in the top half of the high-school group.”

E em Portugal, também será assim? Também é muito melhor estar na metade mais pobre dos licenciados do que na metade mais rica dos trabalhadores com ensino secundário completo?
