How about Brian Chesky (son of social workers), Marc Andreesen (son of seed factory worker), or just Jeff bezos with a pretty shitty family background:
At the time of Bezos' birth, his mother was a 17-year-old high school student and his father was 19 years old.[18] After completing high school despite challenging conditions, Jacklyn attended night school while bringing Bezos along as a baby.[19] After his parents divorced, his mother married Cuban immigrant Miguel "Mike" Bezos in April 1968.[20] Shortly after the wedding, Mike adopted four-year-old Bezos, whose surname was then legally changed from Jorgensen to Bezos.[21]
