Which of you has disability insurance?

The damage value - quite simply - 1000 € per month, 12 months 30 years equals 360 K€. Some receive 2000 €, others are only unable to work for 15 years... perhaps it is a bit less. But it is indeed existentially threatening.

Especially since my insurance pays back a significant portion of the premiums...

With at least 7% interest and compound interest? Without compound interest, it can quickly happen that you lose a six-figure sum here with high certainty and not, as in BeHaElJa’s example, in 0.00001 percent of cases. : Frontal crash with a compact car against another car at the age of 30 resulting in death. 50 years of life lost. With an SUV/truck/... in our example, you would have survived with minor injuries. And now? Buy an SUV immediately because it’s (statistically proven) safer? Or could it be that in life there are a number of risks, which even when all taken together are highly unlikely. A large part of disability insurance cases is, for example, cancer. Either you beat the cancer and return to work, or you die from it. Decades of payments are the absolute exception and regularly end up in court because insurers then try everything.

Why should the money earn interest? It's not a profit-making business for me... In the best case, I lose the bet and get some nice money to make a special repayment - or just blow it. And I definitely won't sink a six-figure amount there... You have a wrong perception regarding the purpose of an insurance.

I have no disability insurance. Years ago I consciously decided against it. Maybe it would help me now, maybe I would still be arguing with the insurance company. Who knows, but as someone "affected," I would decide the same way again. By the way, I don't know a single case in my circle of acquaintances where the disability insurance really paid out unconditionally.

That is my personal attitude; everyone must decide that for themselves.

75 EUR per month invested long-term in the stock market at 7% results in 180,000 EUR after 40 years. If you get the 75 EUR back completely without interest, that amounts to 36,000 EUR. So you give up over 140,000 EUR.

Who says that I invest 75 euros per month and that for 40 years?

Your assumptions are, as so often, purely theoretical without any practical relevance

Moreover, the comparison with stocks is flawed - they are not an insurance. You still haven't understood that any insurance policy is simply a bet? No profit distribution planned by the policyholder...
