No, there are immigrants who want to dwell in high trust societies and contribute to that. Who are welcome! If you want this and want to participate in it - you are a enrichment to the world and the society you want to partake.
But if you push for a lowtrust society, because these "upvalue" security providers in daily life and you think you must re-educate your fellow man away from "stupidity" towards being eternally paranoid on the lookout, you are a detriment.
If you plan to actively prosper from pushing the scam parasitism and decay on "suckers" or just poisoning a high-trust society with low-trust fabrications - you are the economic equivalent to a lethal parasite or contagion.
