Take a look at this Chomsky presentation, time it around 46:30. It seems that the most rational prediction would be that we are heading for another financial crisis, since financial systems are running a quote “Doom Loop”: Make huge gambles, make huge gains or fail. In the case of failure, get bailed out. This pattern of behaviour is rational, seen from the point of view of the financial sector, given the current environment. So, the good question is, what would the rational course of action be for us, the citizens, given that the financial sector is apparently acting, fully rationally, inside a Doom Loop?
The rational question would be, when is the next financial crisis coming? Given a good prediction of this point in time, how should we rationally act, e.g. in the real-estate market? If we should aspire to make rational decisions, we should not hope that another financial crisis will be avoided. We should expect it, and make rational decisions based upon it. For our own gain, if we so desire. Now, how do you do that? That is another question. It seems obvious that decisions in many areas should be influenced by this apparent fact, e.g. decisions in real-estate, entrepreneurship, family planning. If there is money to be made, somehow, in betting on the next financial crisis, maybe that would be the rational thing to do.
