Couples with high income, inheritance, people who live on credit and debt, &c. Not many can afford a new house with a single income, let alone to support a family with kids, maybe not 1% earners but definitely around 10%. A friend of mine has kids, they spend 60% of their household income on the flat they rent (2 salaries, both a good 20% above average for the city), that's before the car, heating, electricity, kids spendings, food, &c. and they're already one hour away from the city center by train There isn't much up for debate I'm afraid: https://assets.bwbx.io/images/users/iqjWHBFdfxIU/ifomkf25BuWY/v0/-1x-1.png https://assets.bwbx.io/images/users/iqjWHBFdfxIU/ifomkf25BuW... https://fred.stlouisfed.org/graph/fredgraph.png?id=QDEN628BIS&nsh=1&width=600&height=400 https://fred.stlouisfed.org/graph/fredgraph.png?id=QDEN628BI... https://www.statista.com/graphic/1/416207/average-annual-wages-germany-y-on-y-in-euros.jpg https://www.statista.com/graphic/1/416207/average-annual-wag... https://www.researchgate.net/profile/Carlo-Jaeger/publication/255612076/figure/fig9/AS:669547560452096@1536643986011/Widening-discrepancy-between-wage-ratio-and-productivity-in-Germany.png https://www.researchgate.net/profile/Carlo-Jaeger/publicatio... https://www.move.org/app/uploads/2020/04/Home-price-changes-since-1975-1024x572.png https://www.move.org/app/uploads/2020/04/Home-price-changes-...
