This is no better than saying we can’t fix schools until we “fix poverty.” Anti-poverty policy, though costly,
is very effective in the U.S., and education is only one among
many factors that
contribute to poverty and inequality (as is partially evident in the fact that much of the rise in inequality in the U.S.
has occurred among similarly-educated people).
In addition, while improving public education will help millions of people, the benefits will elude everyone who is beyond school age. These people need help now, and no amount of K-12 education reform will provide it. [emphasis mine]
