The best we can do is make sure the country is healthy (financially speaking) so that we have the resources to do what needs to be done in unexpected situations. Of course, our Federal Government and many state governments (e.g., Illinois, California) have made sure to squander our resources during normal times, so that when the unexpected fractal / black swan event comes, we don't actually know if our governments have the resources to handle this. QE Infinity?...er, ok...will that work...who knows? More legislated debt?...will that continue to work...who knows?
