Do you have any links for what you consider to be the current state of economics? I will the first to admit that I am not an economist, but I do try to at least keep an ear out for what may be current and certainly in terms of what I've been hearing from a layman's perspective, for the most part my comments remain valid against current economics work. That said, it's also why I prefaced my comments that they were primarily centered from several years ago back when I was in college and that the analogy was mostly personal opinion. If it is personal opinion founded in ignorance, I am happy to be proven wrong or shown cool things, if you are interested in a deeper discussion beyond insults.

Certainly, the models that we see in day to day political discussions and popular/lay culture have not seemingly progressed much beyond the macroeconomics courses I took in college, but again I'm willing to admit I certainly have my biases/blinders. Also, I'm sure that dynamic models exist, I was more curious if there are economists that have played with models more closely aligned with my physics analogies, specifically.

Thus far the one of most interesting things in economics right now, to myself at least, is I have done some reading on some of the work of theorists in Modern Monetary Theory (MMT) and I liked where it seemed to be heading (not to mention its ties to turn of the last century Social Credit theories/works). That certainly seems close to what I'd expect/like to see more of in economics, but correct me if I'm wrong, it still seems "fringe" in the current state of economics.
