Over the past 12 months, an American businessman became the world’s first 100-billion-dollar man. But Donald Trump’s wealth sank during his first year as president of the United States. Those are just two findings from Forbes magazine’s latest report on the wealth of the world’s richest people. The report, released on Tuesday, says the world now has 2,208 billionaires. They have a combined wealth of $9.1 trillion, an increase of 18 percent compared to one year earlier. Forbes says Jeff Bezos is now the richest person on the planet. Most of his wealth comes from shares of stock in Amazon, the e-commerce company. Amazon shares rose 59 percent during the past year.
