Good luck timing it. "The market can remain irrational longer than you can remain solvent."

There isn't always a mechanism that will translate being-right about some fundamental fact into making-money from it.

P.S. It isn't trivially "solved" by someone setting up a gambling scheme either. Many people who are right will still lose because they didn't also guess when other people would start to agree with the conclusion. Plus there's the time-value of money for things which take longer to play out.
