Transcript
- Lucas: Germany added about 330,000 workers from non eu countries last year. That's the highest number since the country started keeping records — and it's directly tied to a law they passed in 2023 called the Skilled Immigration Act. Luna: Right — the one that introduced the 'opportunity card' and lowered the salary threshold for the EU Blue Card. Lucas: Exactly. And the reason this matters so much right now is timing. The first of the German baby boomers — the Jahrgang 1964, the biggest birth cohort in post-war history — started retiring last year. That wave will crest around 2029. Luna: So you've got the biggest generation ever leaving the workforce at the same time you're trying to keep the pension system solvent. Lucas: Precisely. Germany's pension system is pay as you go — current workers pay for current retirees. The ratio of workers to pensioners has been dropping for years. In 2015, you had about 3 workers per retiree. Today it's closer to 2.7. By 2040, if nothing changes, it could fall to 2.1. Luna: And that directly affects the contribution rate. Right now it's 18.6 percent of gross wages, split between employee and employer. Lucas: The German government has a legal ceiling — it can't go above 22 percent without a new law. The Bundesbank has modeled this. Their estimate is that without additional immigration, the contribution rate hits 22 percent by the mid-2030s. With sustained net immigration of roughly 400,000 working-age people per year, they think you can keep it under 22 percent through 2040. Luna: Okay, so 400,000 net — that's gross arrivals minus people who leave or retire. Last year's 330,000 non eu additions is in that ballpark, but it's gross. Lucas: Exactly. And this is where the policy detail matters. The Skilled Immigration Act wasn't one law — it was a package. It lowered the minimum salary for the Blue Card from about 58,000 euros to 43,800. It created the 'opportunity card' — a points-based system for job seekers who don't have a specific offer yet. And it removed the requirement that job offers had to be in a 'shortage occupation' to get a lower threshold. Luna: That's a big shift. Before 2023, if you wanted a Blue Card, your job had to be on a list — engineers, IT, healthcare. Now it's more about qualifications and salary. Lucas: Right. And the early data suggests it's working. In 2023, Germany issued about 80,000 Blue Cards. In 2024, that jumped to roughly 120,000. The opportunity card only launched in June 2024, so we don't have full-year numbers yet, but initial applications have been strong — mostly from India, Indonesia, and Turkey. Luna: So the policy lever is pulling in the right direction. But there's the friction side, too. I've read that visa processing times at German embassies in some countries are still six to nine months. Lucas: That's the biggest bottleneck right now. The Federal Foreign Office added about 600 new staff for visa processing in 2024, but the backlog is significant. The German Economic Institute estimates that every month of delay costs the economy about 1.5 billion euros in lost output. And for the pension math to work, you need these workers to arrive and start paying into the system. Luna: It also matters what kind of workers they are. A 28-year-old software engineer earning 60,000 euros pays a lot more into the pension system than someone in a lower-wage job. Lucas: Absolutely. And the Skilled Immigration Act is explicitly designed to tilt toward higher-skilled, higher-wage workers. But the integration piece is the wild card. The OECD has a great study on this — they tracked migrant earnings trajectories in Germany over the last decade. The median time to reach wage parity with native-born workers is about seven years. For those from non eu countries, it's closer to ten. Luna: So even if you hit the 400,000 net target, the pension contribution benefit is back-loaded. You don't get the full effect in year one. Lucas: Exactly. The Bundesbank model accounts for that — they assume a gradual ramp-up in earnings and contributions. That's why they're projecting stabilization, not a reversal. The contribution rate still rises — just more slowly. And that buys time for other reforms, like raising the retirement age or adjusting benefits. Luna: It really is a fascinating case study in using immigration as a demographic buffer. It's not a silver bullet, but it's a concrete policy with measurable targets. Lucas: You know, talking about policy trade-offs like this — where the numbers are clear but the implementation is messy — that's exactly the kind of thing listeners tell us they appreciate about the show.

It's a small gesture that goes a long way toward covering hosting and production costs. Luna: Yeah, and it helps us keep the show independent — no sponsors to answer to, just the economics we think matter. Lucas: Alright, back to the German case. One more layer I want to add: the regional dimension. The immigration influx is not evenly distributed. About 70 percent of new arrivals settle in just five states — North Rhine-Westphalia, Bavaria, Baden-Württemberg, Hesse, and Berlin. The eastern states, which have the most acute demographic decline, are getting very few. Luna: So the pension system as a whole might be stabilized by national numbers, but the local labor markets in the east continue to shrink. Lucas: Precisely. Saxony and Thuringia have dependency ratios that are already worse than the national average. Their working-age populations have been declining since the early 2000s. And without a regional distribution mechanism — like Canada's provincial nominee programs — the market tends to concentrate newcomers where the jobs already are. Luna: Which is a chicken and egg problem. The jobs aren't in the east because the population is shrinking, and the population keeps shrinking because the jobs aren't there. Lucas: And that has fiscal consequences. The pension system is national, but the social infrastructure — schools, hospitals, public transport — is largely state-funded. So states with declining populations face rising per-capita costs for maintaining that infrastructure, even as their tax base erodes. Luna: That's the hidden cost of demographic change that doesn't show up in the pension contribution rate. Lucas: Exactly. And it's why the German government is now piloting what they call 'Ankerzentren' — anchor centers — in a few eastern cities. These are one-stop shops for immigration, housing, language training, and job placement, designed to increase retention in those regions. The early results from the pilot in Cottbus show a retention rate of about 65 percent after one year, compared to the national average of roughly 50 percent for new arrivals. Luna: That's a meaningful improvement. And Cottbus is an interesting choice — it's in Brandenburg, near the Polish border, and it's one of the few eastern cities that's actually grown recently, partly because of Tesla's gigafactory nearby. Lucas: Right — and Tesla is a good example of the demand side. They've been hiring heavily in Brandenburg, and a significant share of their workforce is international. The local Chamber of Commerce estimates that about 30 percent of new hires in the region over the past two years are foreign-born. So the immigration policy and the industrial policy are starting to converge. Luna: Let's zoom out for a second. Germany's approach is often contrasted with Japan's, which has been much more restrictive on immigration. Is there anything Japan could learn from this? Lucas: I think there is. Japan has also started to open up — they created a 'Specified Skilled Worker' visa in 2019 — but the scale is much smaller. Japan admitted about 200,000 foreign workers last year, but their population is about a third larger than Germany's. On a per-capita basis, Germany is admitting roughly three times as many. And Japan's pension system faces an even steeper demographic cliff — their old-age dependency ratio is already above 50 percent. Luna: So the German experiment is being watched closely, not just in Europe but globally. Lucas: Absolutely. And I think the key takeaway is that immigration is a slow-acting policy. The effects on the pension system unfold over decades. The decisions made today — the visa processing speed, the integration support, the regional distribution — those will determine whether the 2040 projection holds. But the alternative — doing nothing — has a very predictable outcome. Luna: Which is what? A contribution rate above 22 percent, or benefit cuts, or a higher retirement age — or some combination. Lucas: Right. And each of those has its own political costs. So the immigration route is the least painful politically, even if it's logistically hard. The question is whether Germany can sustain the administrative momentum long enough for the demographic tide to turn. Luna: And whether other countries will follow suit. It's a great real-world test of how much immigration can really offset aging.
