The Treasury Department picked an interesting moment to announce a revision in its plans to change the faces on America’s money. Plans to boot Alexander Hamilton off the $10 bill in favor of a woman have been shelved. Instead, Harriet Tubman — one of the most heroic figures in the history of our nation, or any nation — will move onto the face of the $20 bill.

She will replace Andrew Jackson, a populist who campaigned against elites but was also, unfortunately, very much a racist, arguably an advocate of what we would nowadays call white supremacy. Hmm. Does that make you think about any currently prominent political figures?

But let me leave the $20 bill alone and talk about how glad I am to see Hamilton retain his well-deserved honor. And I’m not alone among economists in my admiration for our first Treasury secretary. In fact, Stephen S. Cohen and J. Bradford DeLong have an excellent new book, “Concrete Economics,” arguing that Hamilton was the true father of the American economy.

Full disclosure: I know next to nothing about Hamilton the man and his life story. Nor, I’m sorry to say, have I managed to see the musical. But I have read Hamilton’s pathbreaking economic policy manifestoes, in particular his 1790 “First Report on the Public Credit,” a document that remains amazingly relevant today.
