That $350 billion worth of stocks and exchange rates isn't exactly money as we know and handle on daily life to begin with. More like value perceived on a rather subjective and fickle way over an ammount of assets that hasn't changed at all since yesterday.
Of course, people love to overreact and then come up with stupid claims as "I'm leaving the country now" and other BS, since apparently most humans don't use more than the brain stem and the limbic system before voicing their opinions. Calm down folks...
