Putting the cart before the horse a bit. Borders exist to establish a separation between inside and outside. An awful lot of different things will fall on either side of the line, but to pick out just one of those things and pretend that's the only, or even the primary, reason the line was drawn is silly. It's also disappointing to fundamentally misunderstand what's going on. There are four major elements to national power: Diplomacy, Information, Military, and Economics (the DIME). The author is mostly looking at economics and pretending that's all there is. A nation has a responsibility to act in the interests of its citizens. Sometimes that means acting against the interests of non-citizens. It's a simple, if painful, concept. Analyzing immigration without acknowledging it is silly. Additionally, in a nation supposedly run by consensus of its citizens, it's silly to pretend that the process has failed just because you're unhappy with the speed or the compromise. Slowness and compromise are features, not bugs.
