Reflecting the American debate over taxing the rich, Clinton on Monday addressed participants in her husband's Clinton Global Initiative.
The annual forum brings together leaders in politics, business and philanthropy to tackle the world's biggest problems.
Clinton says the U.S. will help struggling nations become self-sufficient rather than offering traditional aid. She says taxing the wealthy would bolster such growth.
The secretary of state says she's now out of politics. She has said she plans to retire after elections.
