This is also not a permanent situation as also the prices for energy, renovation and other house spendings grow. Elderly people who worked for their house a whole life will just get a small pension and so there will cone a time in which they can't afford the remaining costs anymore as they have to decide between grocery's or house. The decision is easy as you can't eat the house. Additionally they will get I'll and need help which also costs a mass of money so they have to sell.
