We can just make stuff up with aplomb. One day we say the market rises as "investors cheer" good employment numbers; the very next day we attribute the decline to "structural problems" and look forward to a long decline! Were those structural problems not present yesterday when investors were cheering?
It takes some big brass ones to dismiss more than half the world's population as being irrational, hormonally-driven basket cases incapable of serious work. It's even more ironic to make that claim while speaking at UVA, home of two of the most famous fearless female gladiators in all of higher education.
