Thanks for the reply. I appreciate!
But, you used that word 'grow' as a generic term again. My problem is that it doesn't actually mean anything in a generic sense, although, from the way you followed up, I assume you meant GNP. The very idea of GNP as the ultimate measure of anything assumes that all societies are competitive by nature. Example: I live on my island. My island produces all my basic needs, therefore, I could really care less whether your island produces thing-a-ma-jiggers or not, much less how you price them or whether Joe Capitalist's island makes more or less than you. That is to say, you still used capitalism , per se, as the basis for your whole model, and gross measures such as nations as units. That kind of negates the process having any use to individuals at all, since they are relegated to the position of unnamed points in your data collection.
I started life as a manufacturing systems analyst, back when almost none of those systems had been automated. (These days, you can get a degree in the subject area, but there was no such thing then.) What we later saw, was that you can define and automate any actual processes you like - because they are physical circumstances that produce physical things, and can therefore be measured and modeled. What you CAN'T model, is production forecasting. Oh, you can build systems to automate the calcs and check capabilities and capacities and such - but you cannot, no matter what you do, make it forecast accurately. Because that, by its very nature, is guesswork. Some forecasters are better than others, true. But we don't actually know why and they can't explain why, and so it's never been successfully automated. What economic measures try to do is SO much fatter and lives in such a hugely expanded context, that I think of it as the same kind of problem.
I guess, I'm not arguing whether it's useful at all. I'm just having a problem with it holding any actual human relevance...unless you own a nation, in which case, game on?
