The former communists running Russia apparently understand tax policy better than the crowd in charge of U.S. tax policy. Not only does Russia have a 13 percent flat tax, but the government has just announced it will eliminate the capital gains tax (which shouldn't exist in a pure flat tax anyhow).
Here's a passage from the BBC report:
Russia will scrap capital gains tax on long-term direct investment from 2011, President Dmitry Medvedev has said. ...Mr Medvedev told the St Petersburg International Economic Forum that long-term direct investment was "necessary for modernisation". ...Its oil revenues fund, which has been financing the deficit, is expected to end next year, and the government wants to attract more foreign investment to boost the economy.
Sounds like President Medvedev has watched my video explaining why there should be no capital gains tax. Now we just need to get American politicians to pay attention.
