Keep it real? Lol, you're so hip, But you are also incapable of defending your assertions.
Well, so you keep saying. But you seem to be unable to give any examples of assertions that need defending, while tolerating and making festoons of your own.
The fact that you wrote needing an arrow to show "Marx born here" rather implies you dont really understand what capitalism even is.
It does? Or is it rather something you would need to be true, and are constructing the slenderest strawman argument to assert?
Now, you have to try and show how energy is the determinant of wealth - not just a contributory factor, but the determining one.
I don't have to try and do anything. Your task is to explain how theories evolved under one very particular set of conditions might be expected to have any explanatory power under reversal of those conditions.
The efforts by economists and other social "scientists" to decouple economics from energy are enormously and deeply flawed, in a way and to a degree which is almost inconceivable to someone who has a background in the natural sciences, or who believes in generating truths from the use of the scientific method (disclosure: I have qualifications in both, so am fairly well placed to make a judgement).
Turn your statement around, and you get a simple proof by contradiction. Remove energy from economic processes: what economic processes remain viable? Answer - none. The assertion that energy might be merely a contributory factor that has to be explained betrays a pathological attachment to ideology.
I'll go further. We know exactly what level of wealth is sustainable - the level of wealth attainable through the energy accessible by efficient, agrarian societies. And, to return to the thread, the level of debt incurred by this dysfunctional industrial society is far in excess of that which can be sustained by even the most efficient agrarian society.
Now, I'll happily consider any exceptions that you believe contradict that conclusion. I'll also be happy to consider your argument that your philosophies have anything to tell us following the reversal of their most essential (and apparently, for you, unconscious) assumption.
