Well, presumably you're paying to sit in a car with others who have paid more to sit in that car. Given that there are little-to-no extra frills, you're just paying to avoid people who don't have as much extra cash to spend.
Yeah, it's weird. In Europe, on many short to medium distance trains (ie SNCF's TER service) there's often just first class seating partitioned from the commonfolk that offers little more than slightly more legroom and different coloured seating. I guess I could have sat there both ways between Paris and Chartes, as no one came to check tickets in either direction.
MTR's trains between Kowloon and the Chinese Mainland (when I went, MTR just acquired KCR) have a first class car, which I bought partly as it offers forward/backward seating (I wanted to see outside comfortably) and a quiet ride. The second class cars are packed with metallic cattle seating.
