The billionaire boom

The pandemic has been a boom time for America’s richest billionaires.

The wealth of nine of the country’s top titans has increased by more than $360 billion in the past year. And they are all tech barons, underscoring the power of the industry in the U.S. economy. Tesla’s Elon Musk more than quadrupled his fortune and jockeyed with Amazon’s Jeff Bezos for the title of world’s wealthiest person. Facebook’s Mark Zuckerberg topped $100 billion. Google co-founders Larry Page and Sergey Brin gained a combined $65 billion.
