Demographia defines affordability:
Affordability is the ability for any urban household to be able to rent a dwelling for less than a 25% of its monthly income, or to buy one for less than about three time its yearly income. The mobility and affordability objectives are tightly related. A residential location that only allows access to only a small segment of the job market in less than an hour commuting time has not much value to households, even if it is theoretically affordable.

History, Charts & Curated Readings
"Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement; and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it." George Santayana Vol. I, Reason in Common Sense
"History, real solemn history, I cannot be interested in.... I read it a little as a duty; but it tells me nothing that does not either vex or weary me. The quarrels of popes and kings, with wars and pestilences in every page; the men all so good for nothing, and hardly any women at all - it is very tiresome." Jane Austen spoken by Catherine Morland in 'Northanger Abbey'
