That’s the thing, though. There IS solidarity, as meaningful and deep as anywhere else, it’s just differently focused.
A metaphor I use is that when I lived in Cameroon, I had a small yard in front of my house that was filled in with gravel and dirt. Ringing the yard were trees with fine, narrow leaves and gorgeous yellow flowers. Naturally, these leaves and flowers would fall in the yard, but never in large quantities, just what you’d expect to find in a yard. I ignored the local custom of laboriously sweeping the yard several times a day with a small broom, because why would I sweep the dirt?
Well, Cameroonians hated it. Pretty much everyone who visited would say “Your yard is so dirty!” People would send their kids over at dawn to sweep it before I woke up. People gave me gifts of brooms. It really just did not go over welll. Eventually, I gave in and hired someone to do the sweeping, as obnoxious and uneccesaary as it seemed to keep a pristine patch of dirt.
In my mind, that space was “yard space” and not expected to be particularly clean. In Cameroon, that space was considered living space, and having leaves all over it was pretty much the same as having leaves all over your living room.
Later, I went to China, where in most places it’s customary at all but the finest restaurants to throw bones, gristle, sunflower seed shells, orange peels and used napkins (and even spit) right on the floor. The lunch place I used to go to would develop a two foot-deep pile of trash on the floor during the lunch rush. This was cleaned upr egularly, and nobody seemed to mind.
A lot of people walk away thinking “My God, Chinese people are just dirty.” But that’s not really it. The floors in private homes, for example, are typically pristine. Shoes are always removed at the door, in part because they’ve been traversing all kinds of gross things like restauarnt floors. Just like my yard in Cameroon was “dirty” space to me and “clean” space to Cameroonians, a restaurant floor is a “dirty” space in China, while it is a “clean” space to Americans. It’s not that one group of people is just cleaner or dirtier than the other group (despite the Cameroonians thinking I was clearly a slob), but it’s that these values are expressed in ways that may be unrecognizable to outsiders. Generally, though, things tend to balance out into a coherent system.
I think the same thinking applies to any number of cultural observations.
