Construction costs are currently skyrocketing

The statistics do not include all the inheritances, and those are what really matter. One of our family members is currently building, and their income is like ours, but the plot of land came from the family and didn't immediately consume the first 300k. Additionally, there was 100k gifted from the other side. And so it still somehow works out in our case, and in the other case now very easily and with much more luxury.

what kind of nonsense table is that. Surely not only 6% of the population are richer than us OMG - where can I enter wealth?

You just have to read the underlying study before calling something "nonsense." It explicitly and exclusively deals with the weighted household net income and only that.

To belong to the top 5%, a two-person household without children needs 6,200 EUR net...<
That’s two well-paid full-time employees at any ordinary company, no chief physician, no star lawyer.

What makes this study interesting:
To belong to the top 5% with two children under 14 years, a household net income of 8,700 EUR is required.

I build without inheritance, without generous family contributions in the five-digit range, and since yesterday (2 adults, 2 children 5 and 0) belong to the top 30% income earners... it still works out, I am sure... but without much material luxury...

Well then, congratulations on the new arrival,

The statistics only prove that Germans are simply not rich. I recommend the book [„Das Märchen vom reichen Land“] - it impressively shows that Germans may have good incomes but hardly any wealth. The pension system is pay-as-you-go and there is no capital stock there. What use is 4,500 net as a single top earner without an inheritance because I come from "poor" backgrounds and have to build something myself, if my neighbor "only" has 2,500 but comes from a good family and has land plus family equity? You don't catch up on that; you build it over generations.

Intergenerational justice would be if the state didn't take so much and every generation had the same opportunities to build wealth.

Well then, congratulations on the new arrival,

Thank you very much. Born into a very turbulent time, we hope for the best.

That would only be achievable through an inheritance tax that takes 50-75% of the inheritance without any exemptions.

Because the exemption of 400,000 EUR per child alone already ensures that someone can simply buy "my" house with cash, while I have to work for 30 years for it...
