Building proposed: "It will be too expensive! We need housing for those making 10% of median income, not for those making the median income!"
Building mid-construction: "This building is unbelievably ugly! How could we let this happen to our town?!"
Building completed: "This building is completely vacant! Why did we allow this to be constructed? It's just proof we should never build anything again, it's not needed."
18 months later, building fully occupied, lots of happy residents with mixed incomes: Silence, because they are too busy complaining about all the other buildings.
And now people have forgotten that almost all the problems cars solve today are problems caused by cars in the first place.
