Right, so my question is why did those enormous unemployment surges happen without the same kind of tariffs that Trump has? They certainly aren't a necessary trigger, could they even cause a major contribution?
I think the true answer is that nobody really knows what pieces are in play let alone how they all interact -- very few economists predicted the housing crash. So when you see lists of things like this, who knows? It looks like throwing spaghetti at a wall to see what sticks.
