I understand the individual's reason why they don't want a high-rise in their backyard. But having a new development 3km down the road really doesn't affect your home. But in cities with lower ownership percentage, everybody is feeling the heat when you just cannot afford to move if you're not a top earner because your current flat would cost twice as much since you moved in ten years ago. Rent as a percentage of income steadily rises, 30% was the maximum recommended value, which is now considered good, 50% is now accepted. Germany has relatively low incomes and high taxes, people are clearly feeling it. Yet still, they re-elect politicians who block large-scale developments in open areas. I've lived in Hamburg, they have plenty of space that can be easily developed and integrated into the public transportation network, but they don't. They wouldn't even need to build it themselves, they'd just need to allow private investors or housing coops to build. But they don't, because ... I don't know. Change is bad? It's too good of a topic to bemoan and win elections with, because people are too simple to see that they've been running the government for 50 of the past 55 years? Landlords paying them off? I don't know.
