Legendary investor Ray Dalio has praised China's "common prosperity" policy, and said the US economy would benefit from a similar focus on equality. Dalio, the founder of hedge fund Bridgewater Associates, also said the US is a riskier place to invest than China, because its competitive advantages are in decline. The subject of China is highly divisive on Wall Street, where leading financial figures are debating whether it makes sense to put money into the second-largest economy in the world.
