All the three cannot be pursued simultaneously, and at least one should be sacrificed. Which one has to be sacrificed? Well, it depends upon country-specific situation and available policy options.
This reminds me of an old adage in Hindu mythology, which is somewhat similar to impossible trinity: that the idols of Brahma (the creator), Vishnu (the preserver), and Shiva (the destroyer) cannot be kept under the same roof! Among three, who should be kept out? There is no rule or convention.
