"In 1930, a year into the Great Depression, John Maynard Keynes sat down to write about the economic possibilities of his grandchildren. Despite widespread gloom as the global economic order fell to its knees, the British economist remained upbeat, saying that the ‘prevailing world depression … blind[s] us to what is going on under the surface’.

Today, that is still up around 38 hours"
