Electrifying large swaths of the South and West changed how people lived and worked every day, how their cities grew and their farms survived. The G.I. Bill, to take another of a thousand examples, was intended to reward veterans and stave off a postwar depression, but it also opened up new possibilities of learning and travel (and therefore work) for millions of young men. This blurring of the cultural and the economic includes the civil rights legislation of the 1960s, which threw the weight of the federal government behind the struggle of African-Americans to go about their daily lives with hope and dignity and which did not alienate every white person in the South.
Today’s Democratic Party, with its finely calibrated, top-down fixes, does not offer anything so transformative. It seems scared of its own shadow, which is probably why it keeps reassuring itself that its triumph is inevitable.
