Peter Schiff was giving in the years 2002 until 2008 about the overstimulation of the economy and the housing bubble that resulted. He nailed what was coming almost perfectly.

It is virtually impossible to figure out the exact timing of when bubbles will pop, but the symptoms of those bubble can be rather obvious.
I remember watching a panel discussion chaired by the Economist. In discussing that phenomenon the host asked the panel how far in advance of a crash is too early to start warning about the bubbles. Peter Schiff had been warning about "The Great Recessions" for years before the bubble popped and was repeatedly derided for his warnings, and yet he was absolutely spot on as to what was happening.
One of his critics was NY Times writer, Paul Krugman, had won a Nobel Prize in economics. In fact, Krugman had written a column calling for the Fed to
create a housing bubble to get the economy out of the doldrums after their earlier dot.com bubble had burst. After the housing bubble burst Krugman wrote an article, "How Did Economists Get It So Wrong?"
