In summary, I have argued that, despite our dedication to the idea of a higher education system open to all, we are not doing a very good job of leveling the playing field. The result is that opportunity is still linked too strongly to class. In the longer term, the solution needs to involve improving the K–12 system. It also needs to involve making learning and access to skills beyond this level a less costly process and one that does not necessarily require four to six years of college. In the near term, more could be done to better inform students and their families about available options, including the availability of financial aid for well-prepared students from low-income families; the importance of matching one’s interests and skills with what different institutions have to offer; and the availability of more work-focused career and technical training for those most likely to drop out of college saddled with too much debt.

These findings, which suggested that income inequality is bad for the health of the whole population and not only for those with the lowest incomes, were seen to have important implications. Reducing the inequality would be in everyone's interest, including those with higher incomes.
