> Can you show me a place with high local productivity and low rent?

Put the following prompt into your favourite AI and enjoy the reading:

"How do rents relate to productivity in the area? How does Vienna compare to San Francisco?"

Vienna? World famous for publicly-funded housing construction?

Try this one: "Create a simple analysis approximating how much higher rents would be in Vienna if not for the aggressive public subsidization of supply"

In any case, Vienna has a good system! But it's not that it avoids high productivity → high rent, it's that it splits rent into subsidy costs and rent.

In other words, the amount of subsidy + rent required will grow with local productivity.
