If you want to guilt the American public into opening the borders for eventual ballot box domination through population shift, you've got to make the public think that this mess is Trump's fault, and that the only decent thing to do is open the borders to everyone.
The way to do that is to drag your feet on the Wall and other security measures, so more people enter, and to also deny funds for care and facilities, so the mess you create looks more and more awful every month.
Complaining about Wayfair is consistent with that strategy.
