Social exclusion is obviously difficult to measure, but as an overriding framework, I think it's incredibly valuable. I think working towards social inclusion, however that gets defined, is a good way to go; it's a dignified way to go.
I would agree that we do need to set specific targets. There are ways you can do that when you're looking at social inclusion. You can look at things like a deprivation index, which combines measures of income poverty with lack of certain goods you would expect an average person to have in society.
I'm very much behind moving towards a model that has a lot of history in the European Union, and that is social inclusion.
