Kapito joined
First Boston in 1979 after graduating from Penn and started in the Public Finance Department. He was hired by
Larry Fink to work at First Boston, where they were instrumental in pioneering the
mortgage-backed security market in the United States. Kapito left First Boston to complete his MBA degree and returned to the firm in 1983 in the Mortgage Products Group. In 2022, he warned about product shortages and said that "a very entitled generation that has never had to sacrifice" was experiencing inflation for the first time. The comment received backlash from news opinion pieces, which pointed out his large salary and net worth. Kapito serves as a member of the board of trustees of the
Wharton School of the University of Pennsylvania and as a member of the
Harvard Kennedy School Executive Education Faculty. He is also president of the board of directors for the
Hope & Heroes Children's Cancer Fund, and president of the board of directors for Periwinkle Theatre for Youth, a national non-profit arts-in-education organization. ==Personal life==
