I'm glad you mentioned Flint though. I assume most Americans here know about Flint's issues - but they realise the USA is a big place and that's only one town. Well, China's a big place too. Yeah, it can improve, a lot. But this godforsaken hellscape that people seem to imagine all the time is just not real.
People in places like Flint aren't dead either.
