Possibly. Or it is entirely possible that a downturn could change the fundamentals and lead to a situation where the market never actually self-corrects. Or at least self-corrects to where it was prior to the downturn. There is also the question of, assuming the market will self-correct, how long of a time period that could be. If the market would take too long to self-correct what are the chances that a mass of people push for a "solution" that could be much worse than what is being done currently?
That only proves that rushing for an answer is foolish.
