Both US candidates have economic experts advising them. Whose advisers predicted the crash, and which candidate modified his economic policies to accommodate the changed economic environment?

Rhetorical questions of course- neither is the answer to both. Up to a few days ago, the rules of the economy were cast in bronze, and implemented by an ethereal priesthood whose credentials were unchallengeable. Unlike the contest between Elijah and the Priests of Baal, there simply isn't another religion waiting to take over. Social Marxism was once an alternative, but spoilt its appeal by building its own cult of human sacrifice until overthrown a couple of decades ago- an event which only added to the credentials of the free (for them) marketeers.

So the best preciction I can give is that things will get back to normal as soon as possible, there will be a decent period of mourning during which CEOs will forego half their deserved bonuses, the costs will be extracted from those least able to pay, and eventually everyone will pretend that they've forgotten about it.
