They’ve already explained that China has more economic data to determine that theoretical cap location, so you, not being Chinese yourself, are basing your cap entirely on vibes with no insight on to how it hurts or helps Chinese people. It’s just as arbitrary a number as the equivalent question one could ask you- Give me a hard number of people who should be dirt-poor in China today to prevent billionaires. Quick economic development (with the help of leashed capitalists) has lifted so many out of poverty and it seems you would happily undo this purely because rich people exist and it isn’t pure enough.
