I'm interested in the Euro aspect simply from the point of view of wanting to see the light at the end of the tunnel of the current crisis. As long as uncertainty prevails over its future then it's hard to see from a global economy perspective how things will be put right (not that such an end state theoretically exists) and what time-frame we might be talking about. As things currently stand its seems a bit like we're staring into a big black hole (I'm speaking metaphorically and not about my own position, which is fine, thank you very much ).
All these other things you refer to, housing benefit etc., are highly relevant and seem a bit more certain than the big existentialist crisis overshadowing it all and, in my opinion, preventing us from having a clue about when and how things will improve. At such times it's very hard to see were general confidence will emerge over the economy. Just a thought.
