I don’t see why we have to contrast the US and China so that one is a good guy and one is a bad guy. Has the US exploited the rest of the world since WWII for our own financial interests? Yes. Do we have an increasingly authoritarian government seeking to eventually crush internal dissent? Yes.
None of that makes China good.
If you don’t want to talk about Tiananmen Square, talk about China forcefully relocated migrant workers ahead of the Olympics in 2008. Talk about China sending Uyghurs to reeducation camps and forcefully sterilizing some of them. Talk about how China forced women to abandon/ abort babies for 30 years throughout vast swaths of their country. Talk about how people residing in China can’t actually talk about any of these things, to the point where citizens of Hong Kong fought back with violent protests and many fled to resist their encroaching authoritarian hand.
Did China raise more than a billion people out of brutal poverty in a single generation, and was it one of the most impressive and important developments of the last century? Yes, absolutely. Is an authoritarian technocracy better able to deal with the issues facing humanity in the near future like climate change? Potentially.
That doesn’t mean China’s citizens enjoy civil liberties.
Your baseline assumption here is that interaction with another person is burdensome. Most people don’t feel that way, and if they do, they probably don’t work in the service industry.
So, presuming the doordasher finds human interaction to be neutral (neither good nor bad), and understanding that the customer is not making the joke at the expenses of the door dasher, I fail to see how this is a problem, even if the dasher doesn’t get it. Someone trying to share a joke with you, even if you don’t get it, is usually perceived as friendly.
