To be fair, your point should be fairly easy to prove if it's not hyperbole. You're basically saying, "I'm right because I understand the economy better than you do." You also get the nice benefit that if you are right, you can gloat in two years, but if you're wrong you can just not bring up the subject again. There's no accountability for your argument.

Note, this is what makes fortune tellers and psychics so successful: They only ever bring up the times they were right (or the times the outcome was ambiguous enough they can claim to be right). Surely we should trust them.
