Separate to the "(non)-deterministic" question which would detract from this discussion.

One part we also fail to consider is that there is a feedback loop between all the individuals in society and any large economic levers that get pulled. This along with all the complicated interactions that are a result of the specific imperfect set of information each individual has makes this problem next to impossible to fully model. At best we could have approximations and models that abstract that complexity away. We approach something similar to the N-body problem in physics, which on some level I'd argue is simpler even as we have specific equations government their behavior. Not so the case for humans and their "internal" decision making process.
