20. Maria Franca Fissolo – $23.4 billion
Imagine having enormous amounts of Nutella all the time and getting money for it. Doesn’t that sound like every person’s dream? Well, we should all both thank and envy Maria Franca Fissolo – she was the one who made the taste of Nutella, but she’s also the one to have everything we dream of. We don’t know whether we’re more jealous or grateful right now.
