How a tax begat bebop.
During World War 2, a federal excise tax was imposed on supper clubs to raise funds from their wealthy patrons. According to Eric Felton in The Wall Street Journal, this so-called cabaret tax imposed a 30% tax at venues that featured dancing to a live band and served food. Clubs that provided instrumental music with no dancing were exempt. Within 5 years, the big band sound was dead, replaced by “a new and undanceable jazz performed primarily by small instrumental groups – bebop. . ..” The cabaret tax was finally eliminated in 1965, but by then the rock-and-roll revolution was well underway.

An Omission a Recommendation and a Prediction
The President’s Council of Advisors on Science and Technology (PCAST) recently issued a report to the President of the United States on propelling innovation in drug discovery, development, and evaluation [1]. It is well worth your time to read the entire report. The Council stated that the pace of new therapeutic development has not kept up with the explosion in scientific knowledge of cancer, heart disease, diabetes, and other devastating diseases. Their recommended actions have the audacious goal of doubling, over the next decade, the rate of invention of new medicines for patients, while increasing drug safety.
