According to the source article in Wikipedia: "“We had very limited money,” Lili Khosrowshahi recalled of the family’s early days in the U.S. “I’d never worked before. I started working full-time, and every penny we earned was put in Dara [and two other son’s] education… and it was expensive. I remember at the time coffee was $0.15 [a cup], and I wouldn’t buy a cup of coffee for myself.”"
