The richest 1 percent have got significantly wealthier in most countries over the past three decades, with the most speculator rise seen in the U.S., according to a new report by the Organization for Economic Co-Operation and Development (OECD).
The research group found that the richest 1 percent's share of U.S. income had more than doubled since 1980, nearing 20 percent in 2012. This trumped the share of income held by the wealthy in other English-speaking countries such as Australia, Canada, Ireland and the United Kingdom.
The OECD report, published on Wednesday, was part of a study into income equality undertaken over the last few years. The organization used the figures to call for reforms to the global tax system, joining a number of top-earners who have called for more equitable regimes, including Pimco's Bill Gross, Berkshire Hathaway boss Warren Buffett and former Microsoft chief Bill Gates.
