You should watch “Peter Schiff was right 2006-2007 2nd edition’ on Youtube. You would not be quite so sarcastic.
He mops the floor with about ten other economists,investment pros,etc.,and he is precisely correct.
The car comment is just his way of saying exports of goods.(IMO).
I don’t know much about Schiff other than some TV interviews and YouTube clips, but according to this bolg post (http://globaleconomicanalysis.blogspot.com/2009/01/peter-schiff-was-wrong.html) he did a lot of damage to his investors. It claims that while Schiff correctly predicted an stock market crash in the US, instead of just shorting US stocks (which would have made money), in the past 1+ year he had his investors short the US Dollar (losing money to date), buying emerging-market stocks (losing even more money that US stocks to date), and buying commodities (losing as much money as US stock markets to date).
One can argue that he accurately predicted the US crash and perhaps even that in the long run may be proven right again, but up to now his alternate investing strategies have been as bad as everyone else’s.
