It isn't just the SuperWankers, it's any attempt to dictate what revenue/spending/deficits are going to be years from now. I'm not saying there's no path dependence, that decisions made today will have no impact on what happens in the future, but they don't really have any predictable impact.
The entire exercise is a waste of time, as our politicians pretend to try to solve imaginary problems instead of dealing with real ones.
