I Was in Favor of Open Borders before This
As I have mentioned before, I don't trust a petition signed by alleged intellectuals, even when I agree with it. The latest example of this annoyance is a petition signed by 500+ economists in favor of immigration. I've been trying to tell my fellow reactionaries that open borders isn't one of those left-wing ideas and now I find they're using tactics pioneered by test-ban activists and environmentalist wackos. Trust cues are important in debates and petitions are an anti-trst cue.
500+ economists who are looking at something independently are unlikely to be wrong.
500+ economists who are joining together in telling each other something can quite easily be wrong.
Clearly, we must restrict immigration in some way. I recommend charging admission. We can build walls along the borders with turnstiles in them. I think $1000 per person should eliminate most of the alleged riff-raff.
