Debunking the Myth: Is Public Health Insurance Really Cheaper?
The debate over a single-payer "Citizens' Insurance" (Bürgerversicherung) in Germany often hinges on a critical assumption: that statutory public health insurance (Gesetzliche Krankenversicherung - GKV) is inherently more affordable and socially equitable than private health insurance (Private Krankenversicherung - PKV). Critics label PKV as expensive, unfair, and unaffordable in old age. But what does the data actually say? As the CEO of a major insurance group, I argue these claims are misleading. A clear-eyed comparison reveals that PKV not only holds its own on cost but offers a more sustainable model for an aging society—a lesson with implications for healthcare debates worldwide, including those about Medicare for All versus private health insurance in the United States.
Cost Trends: PKV vs. GKV Over a Decade
Let's move beyond rhetoric and examine the numbers from the PKV's scientific institute. From 2012 to 2022:
- Premiums per fully insured individual in the PKV rose by 29.7%.
- Contributions per insured in the GKV rose by 37.8%.
This means GKV costs increased 27% more than PKV premiums over the same period. The average annual increase was 2.6% for PKV versus 3.3% for GKV. The narrative of runaway private insurance costs simply doesn't align with the long-term trend.
A Real-World Cost Comparison
Consider a 30-year-old, single, self-employed master craftsman without children. What would his health insurance cost?
| Insurance Type | Monthly Cost (Incl. Long-Term Care) | Key Features |
|---|---|---|
| GKV (Statutory Minimum) | €211.66 | Income-based. Capped at a high-income ceiling. |
| GKV (Statutory Maximum) | €933.64 | For high earners, the contribution is a percentage of income up to the contribution assessment ceiling (Beitragsbemessungsgrenze). |
| PKV (Example: "Master Care" Tariff) | €458.03 | Comprehensive private tariff including private long-term care insurance and daily sickness benefits. Price is risk-based, not income-based. |
For this individual, a comprehensive PKV plan is significantly cheaper than the GKV maximum contribution and offers broader benefits. This challenges the notion that PKV is exclusively for the wealthy.
Addressing Common Criticisms of Private Health Insurance
Myth 1: "PKV arbitrarily raises premiums."
Reality: PKV premium adjustments are among the most regulated in insurance. Insurers are legally required to annually review "triggering factors" like medical cost inflation and life expectancy. Any proposed increase must be validated by an independent trustee. The process is governed by strict laws (Insurance Contract Act, Supervisory Act). The industry has even called for reform of these calcification rules, supported by consumer advocates.
Myth 2: "PKV is unaffordable in old age."
Reality: Many PKV tariffs, including our example, offer age-related premium relief options (Altersbeitragsentlastung). More importantly, PKV operates on a funded model. Over a third of each premium is set aside in "aging reserves" (Altersrückstellungen), currently totaling over €306 billion. This capital is earmarked to smooth out costs over a policyholder's lifetime, directly addressing the risk of higher costs in old age.
Myth 3: "GKV is more socially just."
Reality: The GKV's pay-as-you-go system faces a severe demographic test. Fewer working young people must finance the care of a growing elderly population, inevitably leading to higher contribution rates or benefit cuts. The PKV's prefunded model represents a form of intergenerational equity: each generation saves for its own future health costs. Furthermore, the rapid growth of private supplementary insurance (up 3.5% in 2021 to 28.4 million policies) indicates GKV members themselves feel the need to buy private top-up coverage due to gaps in public benefits.
The U.S. Parallel: Medicare vs. Private Insurance
This German debate has a direct analogue in the United States. Proponents of Medicare for All advocate for a single, public system, often citing the high costs and complexity of private health insurance. However, critics point to Medicare's own long-term funding challenges, similar to the GKV's pay-as-you-go structure. The German PKV model—with its mandatory aging reserves—is conceptually closer to proposals for pre-funded health savings accounts (HSAs) or certain Medicare Advantage plans that manage risk pools with an eye on sustainability.
Conclusion: The Value of Choice and Sustainability
The data clearly shows that the "cheap GKV" narrative is a myth for many, especially higher earners and the self-employed. The German dual system offers choice: a solidarity-based, income-dependent model (GKV) and a risk-based, prefunded model (PKV). Rather than abolishing one, the focus should be on ensuring both systems are fair, transparent, and sustainable. The PKV's €306 billion in aging reserves represent a crucial buffer against the demographic wave, offering a lesson in long-term healthcare financial planning that other nations, including the U.S., would do well to examine. In healthcare, as in many things, one size does not fit all.
