Imagine you are a well intentioned urban planner for a large city.

You have been asked by the city to choose a location for a housing project.

You chose:

Land closer to the center of the city. It is more expensive, but residents would be closer to schools, pubic transport, and other services.

Because of higher rents in better parts of town and other factors, you find that you cannot afford to house all residents on that land.

You decided to:

relocate to cheaper land

You find that the land chosen is low lying and swampy. It requires more funding for strong foundations.

You chose to:

continue as planned

You continue with the planning process and begin building. However, new legislation makes it so that federal funding can only be used to increase the number of residents and not to enhance living conditions. You can decide to:

halt the project 

OR 

allow for an increase in the number of residents
