In perhaps the starkest illustration, economists from Harvard University and the University of Chicago wrote in a recent paper that every dollar a worker earns in a research field spills over to make the economy $5 better off. Every dollar a similar worker earns in finance comes with a drain, making the economy 60 cents worse off.
