A fundamental theory is one that does not predict its own breakdown. So QCD is a fundamental theory, as is Newtonian gravity, but both do breakdown.
It is an interesting point of view. Then I would say fundamental theories are in some sense inferior to effective theories, because we usually do not expect Nature to "breakdown", the prediction of new physics is the best we can get of any theory.
