Alvin Toffler
On 4 August 2007, "The Wall Street Journal" ran a cover story profiling Slim. The article said, "While the market value of his stake in publicly traded companies could decline at any time, at the moment he is probably wealthier than Bill Gates". According to "The Wall Street Journal", Slim credits part of his ability to "discover investment opportunities" early to the writings of his friend, futurist author Alvin Toffler.
