Chief Executive Donald Tsang, in response to a question asked at a luncheon, claimed that the size of Hong Kong's government is small with a roughly 20% share in GDP.
For a place like Hong Kong, where no military expenditure is required, a government that has a 20% share in GDP is definitely too much.
And if you wonder what makes Hong Kong's government so expensive, check out this guy, who is supposedly the "central banker" for the territory. He earns many, many, many times more than that of other central bankers around the globe, and yes including Alan Greenspan. And he is not even a central banker in the real sense!
