It's right that you put "richer" in quotation marks. There is little that annoys me, but the claim that we are a "rich" country annoys me. Lower home ownership rate, lower pension level, but a high lifetime working time. The highest household electricity prices in Europe.
Price level index is okay. The EU is set at a value of 100%, we are at 108.2%.
First, please define rich. For me, rich means that I don't have to worry about whether there will be something on my plate tomorrow and whether I have a roof over my head. Even if I am or become unemployed, the state steps in for me. There is more than enough work so that you can always find something.
For example, if I look at Poland where nurses work in two hospitals and that for 12+ hours a day, but here one job is enough to get by well, then I would say that we live in a very rich country.
Another example would be healthcare. In Germany, almost everything is paid for. In Poland, it is often the case that parents beg for money on social platforms so that their child can continue to live, because the state does not pay for many expensive treatments.
And now that interest rates are rising and fewer people can afford a home of their own is unfortunate but not a catastrophe. Home ownership is a luxury.
