I got 4 cities right, even in their correct order except for one. Kuala Lumpur should be there, and I cannot seriously believe how Ho Chi Minh City (Saigon) is richer than KL in any level. I love both cities but in terms of infrastructure, accessibility, consumer advantages, income, etc. KL obviously outranks Saigon many times over (probably except for the number of tourists who visit it).
I am also doubtful if Jakarta should be there. Jakarta is the capital of Indonesia, but it is strictly speaking a "province", not a "city". It is a nice video though. It just shows that Asia has made a lot of stride in terms of infrastructure, skyscrapers and modern conveniences.
