We need to clarify precisely what Gordon Brown has done here - he is not looking at social care (however defined) per se, he is looking at the COST of social care. More specifically how governments afford social care funding and how vulnerable service users are forced to pay - that is sell their homes.
Both of these aspects are highly politically sensitive and are in a context of other social matters such as housing (shortage of provision, need to build so many more, 5 million persons projected to be on council waiting lists by time of next election, credit crunch aspects of this, etc). Wanless, from my recollection, did not factor in the importance of housing and accommodation to the options presented and - without being an apologist for GB here - it is right for anyone to have to factor in these vital considerations to solutions. I doubt this 'pre-consultation to a consultation' as this was aptly described above will do that - it would need far longer than 6 months anyhow.
One matter we can be sure about is that public sector services such as housing and social care will be very high on the agenda of the next general election. Given that greater than 40% of the electorate is the 'grey vote' and the increasing ageing population the need for politicians of all parties to court such a vote grows day by day. Add to this the power of the elderly lobby (Age Concern, Help the Aged etc, etc) and the importance of older persons matters - specifically having to sell their homes and paying for care become a massive political hot potato.
One of the dangers with this is that all other non-elderly aspects of social care - such as disability etc - will be squeezed to pay for what is seen as funding for the primary political cause (the elderly) rather than what is best for the entirety of social care need. In short, led by targetting political sympathetic funding rather than need whether that be on immediate, medium term or long term bases. This is a perennial pragmatic problem of course but heightened even more so because of the reasons given above.
I suggest that while the above reads as cynical, it is more practical than cynical and, unfortunately, an inevitability.
