Xenophobia and racism, mostly. And yes, it's a solution to the aging demographic crisis many countries face (at least in the medium-term).

I remember seeing a video of a presentation back in the Bush years by some neo-con group that advocated for immigration to Pentagon or DoD officials or something. The argument for immigration was mostly the same: we have an aging population, so we could integrate immigrants (who are statistically younger) to solve this issue. I didn't agree much with the broader idea of the presentation though. The broader idea was that there were still some parts of the world not a part of the global U.S.-led hegemony (mostly the middle-east and Africa), and we must spread democracy and capitalism to them. The argument was that globalism/capitalism ensures peace, and that both WWI and WWII happened because globalism was falling apart shortly before those wars. So, to ensure world peace, we need to globalize the entire earth and bring all countries into the the U.S.-led hegemony, even if that means starting wars to spread democracy, lol.

The birth rates are low because of the terrible environment that doesn't support having and raising children. All you're doing is importing more people who will also barely have any children within a generation or so. Mass immigration is just throwing bodies at the bottom of the pyramid scheme. You can see this in action in Canada where housing is absolutely unaffordable, but large numbers of immigrants are brought in who have to work for shitty wages and live with multiple families in a single rental unit.

The screaming about low birth rate is because corporations want to keep a high labor pool so they can drive down the price of labor while keeping up demand for consumption.

Xenophobia propped up by political groups. Many official immigration programs existed in the 19th century that, when allowed to, had immigrants integrated into society.

Just add a "... Are they stupid?" To the end of the title, and repost in a shit posting community

Why don't fat people hit the gym and eat salad?

Oh boy, you need so much stellaris /s

Because racism

The low birth rates are a concern because they need the bodies to generate revenue so they can take care of old people who will lean on government services.

Why should you care about population decline? Fewer people are good for the climate, but the economic consequences are severe. In the 1960s, there were six people of working age for every retired person. Today, the ratio is three-to-one. By 2035, it will be two-to-one.

Some say we must learn to curb our obsession with growth, to become less consumer-obsessed, to learn to manage with a smaller population. That sounds very attractive. But who will buy the stuff you sell? Who will pay for your healthcare and pension when you get old?

Ok, so what does that have to do with your question…

What age group tends to be the biggest voting bloc, the most xenophobic, the most nationalistic…? Old people. Get those foreign people off my lawn, keep those foreign drug dealers, thieves, and layabouts out of my country.

Then there’s exploitation of foreign labor to undercut wages and work rules of citizens of the country the labor is being imported into.

I’m sure there’s more, but basically it’s a hefty dose of xeonphobia and nationalism along with groups not wanting to literally lose jobs to someone who will do it for a lot less.

This is a part of the SNP's manifesto already, FYI.

God, the comments in this thread are nearly all awful
