Immigration is a little more complex than just economic. There is the population factor as well. There are population problems everywhere but some cultures have people breeding at much higher rates than others. With open immigration, the peoplefrom those countries can easily swarm in and eventually over-populate the countries who were originally on track to achieving lower populations.
IE, my country, Canada; the native population (by natives I mean people with roots here rather than the actual original peoples here) reproduces at about 1.5 children per couple. Yet our population continues to grow because people from other countries come in and have 8+ kids, or bring over their 8 kids. We value our open spaces, most immigrants do not; they crowd into expanding cities. Cities are nice and all but they pollute, they are like a cancer that poisons the beauty of this country. Places like Quebec are criticized heavily for their policies (and I am not French, my background is mostly Swede with a bit of English, Welsh, German, and Danish) without considering that maybe they're right to have it as tough as it is to get into the province. Quebec also does very well in lowering pollution, which is the clear opposite of Alberta which is a backwards province who has heavily increased emissions; they're so backwards that they even ban pet rats and such.
Anyway, I don't think immigration is a problem if the nations share a similar birthrate. Why should we take the brunt of other nations' Malthusian dilema when we can prevent it here? What we need to do is close that book, educate the other nations, increase their medical awareness. BIRTH CONTROL. This needs to be done, otherwise keep their population explosions contained. Let them see the suffering that they bring and force them to reform back home before joining us. The worlds population sits at nearly 7 billion in a world whose water and energy supplies, and environment, is barely comfortable with 2 billion.
I describe myself as a little dose of toxic masculinity.
