More than a fifth of the Irish workforce was employed building houses. The Irish construction industry had swollen to become nearly a quarter of the country’s G.D.P.—compared with less than 10 percent in a normal economy—and Ireland was building half as many new houses a year as the United Kingdom, which had almost 15 times as many people to house. Since 1994 the average price for a Dublin home had risen more than 500 percent. In parts of the city, rents had fallen to less than 1 percent of the purchase price—that is, you could rent a million-dollar home for less than $833 a month. The investment returns on Irish land were ridiculously low: it made no sense for capital to flow into Ireland to develop more of it. Irish home prices implied an economic growth rate that would leave Ireland, in 25 years, three times as rich as the United States. (“A price/earning ratio above Google’s,” as Kelly put it.) Where would this growth come from?
