Feel free to offer real numbers in response then. I could not find any source that listed the number of USD millionaires in Vietnam to be out of the hundreds... when you're talking hundreds out of a population nearing 90 million, then yes, millionaires are rare.
(Should also clarify that my "common sense" is also based on, like you, personal experience. I would just rather rely on actual research, which, again, seems to flatly contradict your claims.)
We can easily find the number of millionaires to be few hundreds. But it's probably only based on stock assets. There are hidden millionaires who own other types of assets, like real estate, gold, jewelry, foreign currencies (not legal anymore) or even cash. Some assets are not in name of the real owners but their relatives. Some people are rich thanks to corruption (which is sadly quite high). And all those people won't disclose their net worth. Thus, it's almost impossible to have an exact number of millionaires (http://english.vietnamnet.vn/fms/special-reports/2712/real-v...)
So yes, I don't have a reliable source either. Though I believe that there are no less than thousands or even tens of thousands. Buy it or not, your choice :)
Just a random story: three years ago, a 66 years old lady owned around 50 millions USD in various types of assets. The thing is no one, including her adopted daughter, knew that before her sudden death. Would her name be mentioned in the list of millionaires? I don't think so.
