A question to the authors of Developing Global Leaders....

This is a good read for people who are moving in from "developed countries " to " developing countries". There are a lot of good example for a first timer.

However as  i was reading through this book a few questions curious questions came into my mind.

One of the question is,

 The authors cite the example of Bob having his first position in a" developing country"  as that in Singapore- I would like to ask the authors how they determined Singapore as a "developed country" though  it is classified as a developing country by WB and IMF. For further details on this you can also check the  wiki link.
