Ah yes, sociology. I’d forgotten, on purpose, most of what I learned in that field.
However, after refreshing myself a little I find you are using the term “collective society” inappropriately. The term, AKAIK, refers to very primitive societies, where there is no division of labor (except by sex) and the every member is tied by a common religion, culture language and so on.
Simply considering taiwan’s modern economy (modern division of labor) you can see how inadequate your description is. Simply considering the presence of four main ethnic groups in the country (Taiwanese, Hakkanese, recent mainland descent, aboriginal) you can see how farcical your description is. Simply considering the presence of gay culture, youth culture, military culture, sports culture, foreign culture (western, Japanese, Korean), and an acrimonious political culture (which splits the population almost evenly between the green and blue camp) you can see how utterly out of touch you are with modern Taiwanese society to describe it as collective.
People do not all eat together (night markets are open till 2am or later), do not dress alike (no more than anywhere else), do not listen to the same music (there are pop classical and folk concerts, there are Chinese, Taiwanese and western opera and dance companies), they do not watch the same TV shows (some watch Sex in the City, some Jacki Wu), do not vote the same, they certainly do not share a common work culture, nor even religious life (there are Buddhists, Taoists, religious Daoists, Confucists, Christians, and many many who worship folk dieties).
In my wife’s family (not at all atypical), her brother worships his ancestors and has special affinity with a local folk god, her mother is a devout Buddhist, her sister in law is a Presbyterian, and her nephew is not being raised in any particular religion except that of independence. My wife herself is a former Christian, a choice (choice, but how is choice possible??) that annoyed her father though not her mother.
My wife listens to modern western pop music (with a special love for American folk), her mother listens to modern Buddhist pop, her brother modern Chinese pop, her nephew Japanese kids’ pop (learned from watching Japanese kids programs). While they all vote KMT my wife does so only because of intense dislike of CSB. (There are other DPP leaders she would happlily vote for if given the chance.)
How is any of this possible in a “collective society?” How is this possible in the society you describe?
Travel around the island and start talking to people. You will notice many local and family specific traditions. You will find people with very singular hobbies and interests. You will also discover in many areas a revival of traditional culture. Old buildings are being refurbished, folk arts and practises rediscovered, even traditional snack foods made available once again. Collective societies do not revive their traditions only to repackage them for urban dwellers seeking to reconnect with the past. Collective peoples live in the past; their present lives are a continuation of the past. They do not need to purchase it.
