The observation of modern finance through the lens of sound money requires an onion peeler. Each time I imagine onions, I think of my soft contact lens patients; the ones who abuse them. I think of the patients who wear them too long or through periods of mild irritation or redness and practice poor hygiene.
Soft contact lenses mask normal corneal sensitivity. They act like tiny onion goggles. With soft lenses in place, one can literally chop onions and not feel the normal irritating sensation at all. The problem is they tend to be the last to know about the trouble.
