Construction costs have surged in recent years, pushing homeownership further out of reach for many Americans. But this isn’t a new concern: In 1978, the U.S. Government Accountability Office warned that rising costs were threatening the American dream—at a time when the median home price was just US$44,300, less than three times the median household income. Today, that figure has climbed past $419,000, more than five times what the median American makes.
