no, really. i'm not going to pretend to be anything but the novice that i am. so here is SOS again:
most of non-capitalist human history until the advent of capitalism in the sixteen and seventeenth century appeared to be doing just fine, critical as some of us may be about this or that aspect of various systems that existed at the time, from seigneurial feudalism to nomadic hunter-and-gather society. In fact, given the exponentially algorithmic technological development of industrial and consumerist capitalism, tremendous wastes have been generated, as anybody who has given even a superficial glance at the global ecological crisis today know all too well -- and this "waste" is not at the microeconomic level of transactional imbalance in supply/demand within a miniscule economic sector but at the catastrophically colossal level of the world threatening all species, which surely ranks as the worst example of resource management in history. By the way, it might also be worth recalling here that the notion of "algorithm" does not originate within capitalism, as the word itself derives from the name of the medieval Persian scientist al-Khwarizmi.
Your friend seems very smart and I'm sure has given this a lot of thought, but I don't find his/her argument persuasive as it is.
Let's assume arguendo that we are on the verge of some kind of ecoological catastrophe.
What we want to know is: is it the case that this catastrophe was caused by capitalism?
In order to figure that out we need at least the following two things:
- A sensible and restrictive definition of capitalism;
- Some knowledge of what controls we need to hold constant to get a picture of the "ceteris paribus" effect of capitalism.
(1) is clearly absent from the above quote and elsewhere your friend is basically question begging in regards to what constitutes capitalism.
(2) doesn't seem to have been considered either, which is unfortunate since we are surely up to our eyeballs in selection bias.
Say that you can divide up the causes of the catastrophe into "capitalism" and "other stuff". What are the relative proportions? It seems to me that some degree of pollution is a natural consequence of a popuation of seven billion people. It's not hard to think of other factors that might contribute.
I'm no expert on these things, of course, so perhaps I'm just talking out of my ass here. But it all seems incredibly vague.
I mean, if we we transitioned some other system, and the catastrophe was averted, where would the gains have been made? Increased economic efficiency? Lower standards of living? Etc? Etc?
