All billionaires under 35 inherited their wealth (except in tech)

Hope I'm not abusing HN since I don't have a question or anything to show, but I was reading this Forbs page [1] where they list the youngest billionaires in real time (daily?), and besides the people that started tech companies (such as Evan Spiegel from Snapchat, John Collison from Stripe, etc.) all the other have inherited their wealth from their fathers/mothers/grandparents/etc.

Some examples:

- Alexandra Andresen and her sister Katharina, one year her senior, each inherited 42% of the family-owned investment company Ferd.

- Gustav Magnar Witzoe owns nearly half of Salmar ASA, one of the world's largest salmon producers. His stake was gifted to him in 2013 by his father, Gustav Witzoe, who founded the company in 1991.

- Elisabeth Furtwaengler, daughter of publishing magnate Hubert Burda and doctor and actress Maria Furtwaengler, owns 25% of Burda Media Group.

- Lisa and her father, Fritz Draexlmaier, preside over auto parts maker Fritz Draexlmaier Holding GmbH, of which Lisa is sole owner.

- Anna Kasprzak, along with her brother André and mother Hanni, owns $1.46 billion (sales) Danish shoe manufacturer, ECCO. ECCO was founded by Kasprzak's late grandfather, Karl Toosbuy, in 1963.

- ...

This doesn't come as a surprise or anything, but I thought it would be something curious to show. All in all, it just makes me feel sorry for those who have to work hard everyday to earn their money for their bread and butter (me included). And it also shows (as many already know) that your initial conditions (wealth, where you were born, etc.) matters a lot!
