Dear Readers,
Our Retirement System Faces Enormous Challenges
Our social security and pension systems are being hit by a double wave: demographic change is stretching the classic pay-as-you-go system to the breaking point, while the climate crisis demands urgent new answers. In this article, we examine how tight financing will become by 2030, why even other European states cannot solve the problem, and which long-tested but modernly interpretable community models can provide us with a liveable and climate-friendly future. Step by step, we explain all the connections – even beginners will be able to understand why we need to act.

“The world would be immeasurably better if we listened more to our common sense, took time for each other, and approached everything with respect – nature, animals, and ourselves.”
Francesco del Orbe

When Contributions No Longer Guarantee Security: The Financing Gap in the Pay-as-You-Go System

Our established pay-as-you-go system is based on the principle of solidarity: today’s working population pays contributions from which the pensions and care costs of the current retiree generation are covered. This system works as long as enough contributors face a certain pool. Due to falling birth rates and rising life expectancy, the ratio of contributors to beneficiaries is falling to around two to one. Let’s calculate concretely:

• 44.5 million employed persons (forecast for 2030)
• Average gross wage: €45,000 per year
• Contribution rate for pension and health insurance: 18.6%

This results in €45,000 × 0.186 = €8,370 contribution income per person per year and around €372 billion in total. However, the expected expenditures for pensions and healthcare will be around €912 billion. Even if all conceivable tax surcharges (income tax, VAT, wealth tax, digital tax) were each increased by one percentage point and completely redirected, only about €120 billion would be added. The resulting gap of over €400 billion per year shows unmistakably: The current pay-as-you-go system is not viable without a system change.

Why This Gap Is Inevitable

• Declining number of contributors: Each new baby boomer generation reduces the quota of contributors.
• Rising expenditures: Medical advances and higher living standards increase care and health costs.
• Limited tax increases: Higher levies eventually break available income too severely and burden economic growth.

Europe Close Together – Collapse Threatens Everywhere

A look beyond Germany reveals: No European country escapes the consequences of demographic change.

• France & Italy: Both are approaching the exhaustion of their “Pension Space” by 2030, the scope for wage contributions. Without drastic reforms, benefit cuts or increasing part-time retirement threaten.
• Austria: Pension expenditures are expected to rise from currently about 13.7% of GDP to 15%. Early retirement and adjustments in indexation are recommended.
• Luxembourg: Plans to extend working life and combine pay-as-you-go and funded systems to avoid a triple burden (few contributors, many beneficiaries).

Europe-wide, the EU projects an increase in age-related social expenditures of three to five percentage points of GDP by 2030. Broader tax bases and moderate reforms compensate only part of this increase, so without funded components, the financing gap continues to grow.

A Return to Community: Generational Villages Reimagined

Given these challenges, it seems worthwhile to think about community living models as they have existed in traditional cultures worldwide for thousands of years.

The Principle of Multi-Generational Living

In such a model, several age groups live close together: young families, working adults, seniors. Each person has their private space, but community kitchen, workshop, event room, and garden are shared. Daily mutual help takes place:

• Older people offer childcare or pass on their know-how in courses.
• Younger people help with household tasks, shopping, or mobility.
• Shared meals and activities promote intensive social relationships and prevent loneliness.

This form of living together reduces individual costs for housing, care, and energy because household appliances, vehicles, and technical systems are shared. Joint resource planning also enables local value creation and strengthens the regional economy.

Practical Example of a Cooperative

A group of interested people establishes a housing cooperative: On a former estate, barns are converted into studios, new units are created in half-timbered houses, and a large coach house houses the community kitchen and event room. A solar system covers electricity needs, a combined heat and power plant provides heat. Vegetables and medicinal herbs grow in the garden; nearby, sheep and cattle graze extensively, which also serves landscape maintenance. Through solidarity contributions, all citizens secure their existence and participation.

Global Role Models: What We Can Learn from Older Cultures

Traditional communities around the globe demonstrate the effectiveness of such models:

• African Villages: Elders Councils regulate conflicts and organize agriculture, livestock, and care. Elders are valued as knowledge bearers and everyday helpers.
• Asian Multi-Generational Families: In Japan and China, until a few decades ago, often three generations lived under one roof. Family members organized childcare, care, and household smoothly together.
• Latin American Comunidades: Community harvest festivals and neighborhood help guarantee food security and social solidarity.

These thousand-year-old traditions show: Social security can emerge beyond state bureaucracy when cooperation, respect, and shared responsibility are lived.

Rewilding as a Climate-Friendly Lever in the Village Context

Beyond social advantages, community villages enable close integration with ecological rewilding projects.

• Extensive grazing binds CO₂ through natural grass growth on pastures.
• Reforestation of floodplains and hedge structures creates habitat for birds, insects, and small animals.
• Community gardens and permaculture areas provide regional food and connect food security with climate protection.

While technical processes for CO₂ removal are often expensive and energy-intensive, nature can store large amounts of carbon through targeted measures – such as afforestation or bog restoration. An active rewilding program in community land projects works doubly: it regenerates ecosystems and strengthens social cohesion.

From Footprint to Earthprint: A New Success Measurement

The footprint measures our ecological burdens. The Earthprint, however, evaluates what we achieve in regeneration and healing.

• Every tree, every flowering meadow, every square meter of bog contributes to the Earthprint.
• In a village with community gardens, orchards, and reforestation areas, these successes add up to a positive earth footprint.
• This indicator motivates active environmental protection instead of passive damage limitation.

Petition and Call: Anchoring Rights of Nature

If we really want to change something, we must not wait. As part of the Global Alliance for the Rights of Nature (GARN), we call for giving the Earth rights and signing our petition: https://www.rightsofmotherearth.com/what-we-do. With every signature, we strengthen the protection of our life foundations and manifest responsibility toward future generations.

“If you really want to be sure that something gets done, then do it yourself!”

Conclusion – A New Path for Social and Climate

The financial imbalance of our social systems is unmistakable. Pure pay-as-you-go financing is no longer sufficient, neither in Germany nor in Europe. But in the crisis lies the opportunity to reshape social coexistence and actively anchor climate protection. Intergenerational villages, combined with rewilding and Earthprint mentality, offer a holistic model: social security, cost efficiency, and ecological regeneration in a sustainable concept. Each of us can take the first step today – in the neighborhood, in the local association, or through engagement with GARN. Together, we create a sustainable world where humans, animals, and nature live in harmony. Be the change you wish to see in this world.
