It's only been a couple of weeks and people are still getting used to the idea. It's going to take months before informal demand reduction starts making a difference years before it sinks in that the party is over and some advanced planning would be a wise and sensible thing.
Dealing with reality now doesn't just mean looking at the bigger picture, it means understanding that the politicians are out of the game - they have no clue what's going on - and everyone is going to have to make their own plans, individually and collectively.
It also means accepting that most people won't be making plans, even now.
They're going to wake up next year in a different world with no clue what to do, and no support. They'll whine about how nothing has been done, then realise that nothing is going to be done for them - and then things will get 'interesting.'
You might see government start to wake up and realise there's a problem then.
Or, given Whitehall's record - perhaps not.
