Efficiency at utility maximisation , like any other kind of efficiency relates to available resources. One upshot of that an entity might already be doing as well as it realistically can, given its resources. Another is that humans don’t necessarily benefit from rationality training...as also suggested by the empirical evidence.
Edit: Another is that a resource rich but inefficient entity can beat a small efficient one, so efficiency,.AKA utility maximization , doesn’t always win out.
