You clearly have no clue about what you're talking about. You obviously don't understand what a model is, let alone how and why it's used, and you clearly don't understand the role models play in decision-making processes.

Furthermore, you are completely oblivious to the reality and application of models in general and economic models in particular.

If you are entirely oblivious to the issue you're trying to discuss, it's pointless to continue discussing it with you.
