I think, unfortunately, the definition of decent in this case is viewed as luxury. Most specifically the concept that everyone should be able to own a house within a reasonable commute of work in a desirable location. This cannot happen while also respecting the idea of properties as investments, the wealthy wanting to be able to purchase disproportionately large places in multiple desirable locations, and the idea that so many people may desire to live in a city that the city cannot possibly take them all.
