There was talk as early as 2005 -- on the front page of The Economist, among other places -- that the US was in the midst of a housing bubble. Who at the time needed to heed this? What would they had done differently if they had? How would the economy, and thus history, been affected?

CONSOLIDATION: Here's an example -- you might say the guy who needed to know this was Alan Greenspan, and if he had taken better notice, he would have been raising interest rates around this time.
