Following a March 4, 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.
