Jonah, I take the point that we have made a great of progress since 1929 that cannot in a sense be “repealed,” but imagine, for a second, that you have been transported back to that most unfortunate year. You could have written that the United States had made a great deal of progress since 1829, and you would again have been right. This would, nevertheless, have been rather cold comfort to the people then en route to their Hoovervilles.
