Forbes released its list of the wealthiest people in the United States and Amazon’s Jeff Bezos leads by a long shot at around $160 billion. Microsoft founder Bill Gates comes in second, while investor Warren Buffett is third. Forbes notes that the rise in tech stocks has boosted the fortunes of many on the list, including Twitter and Square CEO Jack Dorsey, whose fortune tripled in the past year. Despite a $10 billion drop from the year before, Facebook’s Mark Zuckerberg is fourth on the list at $61 billion.
