I also think that energy prices are the most important factor. They need to stay low and we will be in good shape.
Let’s face it, the national debt issue is a can that can be kicked down the road for a long long long time.
Energy prices almost can’t screw up the economy again. We just saw in the Iranian-Saudi-Yemeni situation why not: because production in very suppressed right now by cheap costs. Raise the cost, and production increases.
On top of that, keep in mind who’s currently sidelined: Venezuela, Iran AND Syria.
