I'd like to know how, where and when those surveys were done to produce those statistics. Also, what was the sampling number, the sampling rate, how was the survey done, who done it, etc, etc, and did it conform to accepted practice for producing statistics.
I guess what I'm writing is that I think it's all a load of excreta, and it has nothing to do with the habits of the wealthy and more to do with someone selling dreams to people in order to make himself rich.
