Following a 4 March 2004, lecture on time preference at the University of Nevada, Las Vegas (UNLV), a student complained that Hoppe created a hostile classroom environment by stating that homosexuals tend to be more shortsighted than heterosexuals in their ability to save money and plan (economically) for the future, in part because they tend not to have children. Hoppe also suggested that John Maynard Keynes's homosexuality might explain his economic views, with which Hoppe disagreed. Hoppe also stated that very young and very old people, and couples without children, were less likely to plan for the future. Hoppe told a reporter that the comments lasted only 90 seconds of a 75-minute class, no students questioned the comments in that class, and that in 18 years of giving the same lecture all over the world, he had never previously received a complaint about it. At the request of university officials, Hoppe apologized to the class. He said, "Italians tend to eat more spaghetti than Germans, and Germans tend to eat more sauerkraut than Italians" and explained that he was speaking in generalities. Thereafter, Hoppe told the reporter, the student alleged that Hoppe did not take the complaint seriously and filed a formal complaint. Hoppe told the reporter that he felt as if it were he who was the victim in the incident and that the student should have been told to "grow up".
