Ever the wonk, Hill suggests national programs, private-sector efforts and philanthropic initiatives to strengthen school systems, bridge digital divides, remove racial barriers and reduce the male-female wage gap. (She is painfully knowledgeable on this last point, having endured pay disparities in academia, foundations, think tanks and government service.) It is all solid, reasonable stuff — a longtime Brookings Institution researcher, Hill cannot resist citing its studies — but she lapses into her own sloganeering. “Rather than building back better,” she urges, “America would have to build forward together.”(Italics by author, groan by reviewer.) Bold steps are needed, political will is missing, and even a “Marshall Plan for Middle America” makes an appearance.
