"Strong borders" aka "preserve the needlessly byzantine immigration process". Untold suffering has been imbued upon those lacking the fortune to bypass it and we are all poorer as a result.
You can have strong borders without a byzantine process. For example: Just stamp any entry application with "nope". Predictable, fair, strong, easy, cheap.
Of course, that'd be moving in the wrong direction entirely. It should be easy to immigrate.
