this is a very interesting clip. lots to think about and an entertaining presentation (i particularly like the distribution of wealth comparison of china and the us..china looming over the us like a ghost...)
gapminder is a cool site.
by sense is that the thread title downplays what the op presents in a way...the argument seems more that the idea of a clear, obvious distinction between "developed" and "developing" is a myth. the other main claim--which i think folk really should take seriously--is the uselessness of aggregations for thinking in policy terms--that demonstration happens across the comparison of mortality rates by way of hiv between niger and south africa. policy initiatives have to be "highly contextual" he says, and by "highly contextual" he means that it makes no sense to think in regional terms if the region is simply an abstract container for aggregations.
not sure but that this thread might fare better in politics with a different title.
anyway
this cat love scatterplots.
