Last week I read Inside Intuit: How the Makers of Quicken Beat Microsoft and Revolutionized an Entire Industry. I used to read a lot of biographies—progressive politicians, baseball players, composers, Native American chiefs, kings and queens, diplomats, muckrakers, but I do not remember reading about a single businessperson. Now, almost a decade of trying to figure out how to run a company, I have started to take more interest in capitalists.
