"But quite specifically, an ECB key interest rate hike has absolutely nothing to do with the interest rates on mortgage financing."
What kind of nonsense are you trying to tell us here? Then I really wonder why mortgage financing is no longer offered at 1.xx percent. Logically, the interest rates for mortgage financing rise in real and proportional terms with the key interest rates. Rising interest rates increase the yields of bonds, whose value then decreases. And rising interest rates have an inflation-dampening effect. If significantly fewer people can afford financing, prices will at least no longer rise, but rather fall.
A turnkey townhouse villa, four vacations a year, a fancy and, of course, financed car in front of the door, as well as several other "nice to have" frills are already very unusual for an average earner. But of course, this sense of entitlement has become very, very widespread in recent years. I fear that is now over for the time being and will not return anytime soon. It was simply sick.
Dear Karsten from NRW, no offense but maybe you should just change your profession and do something decent.
