China doesn't have a company valued >1T USD, because there is COMPETITION.
They don't have one Apple, they have Oppo, Xiaomi, Huawei
They don't have one Tesla, they have BYD, Nio, XPeng, Li Auto
They don't have one Amazon, they have Taobao, Douyin shops, JD.
US trillion dollar companies are protected monopolies.
Might be cool for the shareholders, but consumers have to put up with shitty Pixel phones, buggy Windows, overpriced mid Teslas, and Facebook bot-slop.
Chinese consumers get better products for less money.
