It is pretty obvious why that did not happen, in the sense that over a long period the thing has been totally stuck. Once it started it is stuck. Then there is a whole lot of people who are not in it at all. Okay, they eventually will pay it but it could be years later. The values of the properties or houses are problematic, which may be a simple way of saying it, without being too pejorative about it.
