I'm not sure I agree with this. In many parts of the US or Europe, you could easily be in a position where you can afford a car (and need one for work), but cannot afford housing. It's true that you might well still be well off by world standards (a car roof is still a roof), but I think I'd require "food, clean water, clothing and reliable shelter" to be a bare minimum for "not poor".
