The old system, the £23k doesnt include someone's house until you are are in a care home.It really was the worst policy sell of all time. The thing is they started saying difficult choices had to be made and thats why they'd done it then after that stuck they decided to say oh no actually its better than now.
What i never saw discussed is the cost implication
The new system, the house is included straight away. So it does make things worse for many people.
