I doubt US will do a wealth tax; wouldn't oppose it: Bill Gates

World's second-richest person, Microsoft Co-founder Bill Gates in a recent interview said he doubts the US will do a wealth tax, but he wouldn't oppose it. The 63-year-old also backed higher income taxes on America's wealthiest people alongside a call for greater financial transparency. "I don't like that you can have trusts where nobody knows who owns it," he said.
