You won't find IKEA founder Ingvar Kamprad partying with the Russian oligarchs in the Alps. The Swedish billionaire is decidedly un-flashy and has even developed a reputation for thriftiness. According to the U.K. daily The Independent, "Kamprad's idea of a break is fishing or rowing in his native Sweden. He once said that his idea of luxury is buying the occasional nice shirt." Frugality may be relative, though: The reclusive billionaire makes his home in the tiny Swiss mountain village of Verbier. His playground is a vineyard near Hyères in Provence; the winery reportedly produces 16,000 gallons per year.
