It's possible. Certainly the secular press is sounding alarm bells, it's even seeping into the mainstream press. Watch zerohedge.com for the sensationalist view. They are what's called perma-bears (constantly predicting a crash) but they churn out good content from a diversity of sources. The places to watch are Germany and China. When Germany crashes it will take Europe down with it and probably Russia too. Currently Deustche Bank is struggling mightily and multiple prophetic sources cite Germany as the place this crash will come.
China has been in a full scale collapse for years now. The Chinese people are remarkable they have kept the failed system standing up just by their sheer force of perseverance, but the Chinese elites are about to lose everything.
Our family has a personal prophecy through my father in law that we need to be ready by January to weather some severe economic storms. I read an article just today that says all the indicators are that America has entered a recession but that it won't be officially announced until after the election. Some numbers concerning oil inventory and demand suggest that the economy is indeed shrinking and that deflation is coming. This would mean your cash could buy a lot more in a few months then it does now.
Even if nothing happens though and the economy soars on to historic highs for years to come, we're called to live simple lives, debt free and centered on hardwork, and child raising or full-time ministry. So either way our course is clear.
