Much apparent economic growth may in fact be an illusion based on a failure to account for reduction in natural capital.
So with a hundred "modern improvements"; there is an illusion about them; there is not always a positive advance. The devil goes on exacting compound interest to the last for his early share and numerous succeeding investments in them. Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end (Henry David Thoreau).
