Thanks for all the info. For whatever reason, even though I usually have no problem finding and sorting out information about complicated and controversial topics, I find this one (i.e. the general topic of Jewish religious and ethnic divisions) very difficult to systematize, and your comments have clarified a lot. Of course, even I was much more knowledgeable about the topic, I'd still consider it a valuable opportunity to hear the perspective of someone who has some insider knowledge but nevertheless strives for objectivity.
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
