“The education system is an increasingly powerful mechanism for the intergenerational reproduction of privilege.”
— Anthony Carnevale
"The 'income achievement gap' – differences in standard test scores and grade point averages – between children from families in the top 10 percent of the income distribution and those from families in the bottom ten percent has been growing. Reardon has found that the income achievement gap between children from the highest and lowest income deciles is roughly 30 to 40 percent larger among children born in 2001 than among those born in 1976."
That is, if you come from a wealthy family, the more likely you are to test well, and go to and graduate from college. Which strengthens your earning potential, and your kids' likelihood of the same. Upward mobility is becoming impossible.
Takeaway: We need to make education more accessible.
