Interesting question. I would answer no,but Ebola is not a factor for me. Increased domestic terrorism, the vulnerability of big data to a devastating cyber attack. An economy based on unsound fundamentals, and the continuing race to the economic bootom are my reasons. Along with a general increase in anger and rage among the general population, and an attitude of mistrust and a proliferation of violence, both by the general population and law enforcement acting like they are a military force.
