The problem with economics is that it is quite static and some things that are truth in some occasions are stubbornly claimed to be all-times-and-places valid laws.

I am absolutely positive that this is done on purpose and you pointed out some of the reasons why. Yes price is a signal - and people will react. But how come that each reaction transforms into a successful adjastment? The economy does not question this assumption - it just says that's what it is. This is the core of the Western view of man embodied in economics - and it is that a mankind can do anything if he wants. He can find new forms of energy, spoil the nature, than fix the nature and so on and so on... This is our new religion and economics is just a function of it, but the problem is mainly in our heads - we have forgotten where we came from and we even don't know what we are.

One of my kids was STUNNED, absolutely STUNNED to learn that when I was a kid ... we did not have personal computers ... or video games.

I did not want to explain about vacuum-tube black & white TV's or crystal set radio. It may be too much to absorb for the new generation.
