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.
Yes, it can be done, and if we want to have a reasonable future, it should be done.
Vienna's solution is fine but has escalating costs and isn't necessary. Land Value Tax is better.
