Right, so you left out the negation, like I assumed. I wrote that models "shouldn't" do that, but you quoted me as saying that they "should" do so. Anyway, I got your point.

What I'm asking for is honesty as opposed to the perpetration of a giant fraud. I don't think that's asking too much.

I'm not saying we know nothing about economies, so I'm not discmissing the entire enterprise. Commonsense alone tells us much. You don't need to be a scientist to track patterns, reason by induction, and learn a little something about what's going on in the world. The question is whether economics is much more rigorous than that, and whether it's as scientific as economists want to make their discipline seem.
