There has been no bigger debate over the last two years than that over deflation and inflation. Perhaps the biggest deflationist Bob Prechter debates one of the biggest hyperinflationist Peter Schiff in the two videos below. They both believe the same thing, a complete collapse is coming in the next few years. They couldn't be more different in how that collapse will occur. Schiff believes we are heading towards a hyperinflation and Prechter believes deflation will come with a vengence and that banks will fail and people will lose deposits etc. (hyperinflation comes on the back end)
Unfortunately they both are just throwing out scenarios. There is little to go off of to conduct fundamental analysis. Collapse is coming, that can be fundamentally analyzed, how it occurs can't because it is based on social mood and political decisions. For my two cents, I think Prechter will be proven right but not to the extent that he is predicting. Deflation will lead to inflation. Dow will never get to 1,000 like Prechter is predicting. Hyperinflation is a political event and Dow well above 1,000 will cause collapse to jump start massive inflation.
I really think one of the more important things to listen to in 2010.
