The elderly white male club of billionaires is gradually getting a makeover, with more women, racial backgrounds and even young people getting the requisite number of zeroes for their net worth statements. The lowering age was underlined when Forbes announced that Kylie Jenner is poised to become a billionaire at age 20, with her makeup line. While many objected to her Forbes description as “self-made” (they feel she coasts on her family reputation), they should be happy to see this list, with 20 billionaires who have succeeded through their own hard work and smarts.
