The point is the same as the NZZ Article. They write about a speicific subgroup of people rather who their believe they write about. (Or in some cases they just pretend to know. 20usd internet per month?)
The biggest example, as pointend around some internet forums, is the 600+ donation. It 's probably someone who “donate” every month to the church (I don’t know how it’s called that kind of tax)
