In their plan the Swedes refer to generational goals: what sort of country do you want to pass on to the next generation? I think that's the sort of frame we ought to be considering, because it's our sense of obligation to our children and our children's children, and the sense of frustration we have when we're not doing that. So that's a time scale; it's not limitless, but it reminds us of what we owe to succeeding generations.
