Kylie Jenner has been named the youngest ever self-made billionaire by Forbes. But some say Jenner couldn’t be “self-made” because she comes from a wealthy, well-known family. Others pointed out that she rode the social media coattails of her half-sister Kim Kardashian West. Forbes defended its decision, defining “self-made” as someone who built a company or established a fortune on her own, rather than inheriting some or all of it. 21-year-old Jenner beat out previous record holder Mark Zuckerberg, who was given the title at age 23.
