If you are among the fortunate few who grow up poor and manage to earn a bachelor’s degree, you might reasonably expect your earnings potential to rise by the same proportion as that of other people who earn a bachelor’s degree. Your actual level of earnings may not match others, but the percentage increase, relative to a high school diploma, ought to be comparable. This is certainly the case in terms of gender and race. Many economists assume this pattern holds for those from different backgrounds in terms of income, too.
Wages are lower for BA holders raised on low incomes
But it turns out that the proportional increase for those who grew up poor is much less than for those who did not. College graduates from families with an income below 185 percent of the federal poverty level (the eligibility threshold for the federal assisted lunch program) earn 91 percent more over their careers than high school graduates from the same income group. By comparison, college graduates from families with incomes above 185 percent of the FPL earned 162 percent more over their careers (between the ages of 25 and 62) than those with just a high school diploma:


BA = quelli con la laurea
HS = quelli con il diploma
above 185% FPL = quelli che sono sopra al 185% della soglia di poverta'
below 185% FPL = quelli che sono sotto al 185% della soglia di poverta'
Sono abbastanza convinto che in Italia la distanza tra le curve di chi e' nato ricco e chi e' nato povero sia ancora piu' grande.

"Salusa Secundus!" the Baron barked. "What has this to do with the Emperor's prison planet?"
"A man who survives Salusa Secundus starts out being tougher than most others," Hawat said. "When you add the very best of military training - "
"Nonsense! By your argument, I could recruit from among the Fremen after the way they've been oppressed by my nephew."
Hawat spoke in a mild voice: "Don't you oppress any of your troops?"
"Well . . . I . . . but - "
"Oppression is a relative thing," Hawat said. "Your fighting men are much better off than those around them, heh? They see unpleasant alternative to being soldiers of the Baron, heh?"
The Baron fell silent, eyes unfocused. The possibilities - had Rabban unwittingly given House Harkonnen its ultimate weapon?
Presently he said: "How could you be sure of the loyalty of such recruits?"
"I would take them in small groups, not larger than platoon strength," Hawat said. "I'd remove them from their oppressive situation and isolate them with a training cadre of people who understood their background, preferably people who had preceded them from the same oppressive situation. Then I'd fill them with the mystique that their planet had really been a secret training ground to produce just such superior beings as themselves. And all the while, I'd show them what such superior beings could earn: rich living, beautiful women, fine mansions . . . whatever they desired."
The Baron began to nod. "The way the Sardaukar live at home."
"The recruits come to believe in time that such a place as Salusa Secundus is justified because it produced them - the elite. The commonest Sardaukar trooper lives a life, in many respects, as exalted as that of any member of a Great House."
"Such an idea!" the Baron whispered.**Modificato dall'autore il 20.02.2016 13:17**
