He’s the richest man in China and, according to the Bloomberg Billionaires Index, the 19th richest in the world. Now Jack Ma, 54, is stepping down as executive chairman of e-commerce giant Alibaba to return to an old job: teaching school. Money magazine has a quick biography of Ma and how he grew Alibaba “from a website run out of his apartment to one of the biggest tech companies in the world.” The company is now worth $420 billion, and Forbes says Ma has a net worth of $35.1 billion.
