@ Jono - Good points regarding market and planned economies. One thing is for sure however and that is social engineering is being planned. I have been to DCLG events to explain impact of welfare reforms and still have the slides as evidence. In fact the commentary that accompanied the presentation stated that the government expects more movement out of London than followed the blitz.
We need to get a grip on the benefit culture of course but targeting the most vulnerable in society is not necessarily the best for everyone in the longterm.
