It’s a very good explanation in layman’s terms of how the PPIP is designed to overprice assets, whilst giving the impression that they are just helping to set the ‘right’ price.
I think the truth is that those who knew anything already knew that, and the rest of the public is unreachable, even with the best explanation. Besides, the public wants their homes to have as high a market value as possible, along with their equities. As the saying goes, “it’s hard to get a man to understand something when his salary [or wealth in this case] depends on him not understanding it”.
