Richest people in the world

Richest people in the world

It's true that the rich are different from you and me. Not only do they have more money, but many hail from remarkably colorful backgrounds, with fierce passions and oddball interests. Some have emerged from extraordinarily humble beginnings, emigrating from impoverished countries or growing up in a tenement or an orphanage. To learn about the wealthiest people in the world, Stacker compiled net worth data from Forbes as of Aug. 27, 2020.

Many of the people on this list used their smarts and creativity to build giant technology empires, invent sophisticated online tools, transform tiny businesses into global conglomerates, expand a single shop into a global retail chain, or turn a small investment into a fortune. Others were handed their wealth by their birth, given massive unearned holdings in automobile manufacturing, luxury goods, shipping lines, tobacco, chocolates, and cheese production.

Among the top 100 richest, a noticeable number made their fortunes in China, via commercial real estate, cutting-edge pharmaceuticals, e-commerce, vats of soy sauce, or pig breeding. Others played their cards right in high finance with prescient investments and lucrative hedge funds, while still others pulled their wealth from the earth, extracting oil, gas, gold, and nickel.

It's not uncommon for the richest people in the world to be reclusive, shuttling from one luxurious home to another by private jet, protected by walls of security and windows of dark tinted glass. Others bask in the spotlight, looking for their next high-profile conquest or sharing lessons of their experiences with avid audiences.

Keep reading to learn more about the richest people in the world and how they made their fortunes.
