The average expected value of voting for the better party, therefore, is the probability of success (one in sixty million) multiplied by the benefit to Americans (which I’m supposing to be $314 billion), which equals about $5,200 of value to the people of the United States. That’s the sense in which voting is like donating thousands of dollars to (developed-world) charities. For all but the ultrarich, that’s a much better use of time than you could get, for example, by working the hour it takes you to vote and donating your earnings.
