No. Cars and phones are more expensive relative to median Chinese income than they are in the U.S. relative to median U.S. income. You're lying.
China’s per capita GDP is 1/5 that of the USA. If China’s phones are less than 1/5 the cost of American phones, then yes phones in China are actually cheaper. But I guarantee you they’re not that cheap, and so actually they’re almost certainly effectively much more expensive. You’re a disinformation liar.
