What if the economy is a shitstorm? I'm not talking about right now, either; I'm talking about an Argentina-style, complete meltdown. What then? Can it become implausible to do well?
Obviously there's a point at which it could, yes. If you lose civil order, for example, you lose most of the economy. That's what really destroyed the economy of the Roman Empire. There were of course deeper underlying causes, but the proximate cause was plundering and brigandage.
