I am right now in Hong Kong, my 25th visit probably; and I don’t stop discovering. The tram to the Victoria Peak was the first mechanized transport in HK (later than the first trams in my Calcutta, and the clock stopped for us). There was a First class and a Servants’ class! The Servant’s class ran unabated until 1960.
And the British called us class conscious!
The big difference is while rest of the world moved on from classes, segregation, apartheid, and so on, we stick to them and even win elections riding on them. Quite a class, we Indians.
