The commentary makes several good points, but gets off track, in my opinion, when it downplays the need for legislation to reduce legal immigration levels. Yes, the President can achieve this, during his administration, without legislation, and he should do so. However, if this is passed into law, which I hope happens very soon, other Presidents could not then undermine this sorely needed policy change unless Congress went along. President Obama based his questionable legacy largely on Executive Orders, and President Trump has ably demonstrated how easy it is to knock down such a 'legacy' in short order.
