What will Jeff Bezos do with his fortune? The Amazon chief has amassed around $130 billion, and there’s really no practical way to spend more than a fraction of it. “The only way that I can see to deploy this much financial resource is by converting my Amazon winnings into space travel,” Bezos said in a recent interview. By “space travel” he means space tourism and space colonies—“millions” of earthlings living and working in space.

Other people, naturally, feel they have better ideas for all that wealth. One of them is Harold Pollack, a “professor of social service administration and public health science” at the University of Chicago, who suggested in a New York Times op-ed that Bezos spend it on the sorts of things a professor of social service administration and public health science would spend it on. “If Mr. Bezos wants to strengthen America’s future scientific prowess, he would finance intensive math tutoring for about two million high school students every year—forever. . . . If he wants to nourish the high-tech sector that enabled his fortune, he would endow eight MIT-size universities around the world and still have billions left over.”
