Phew, Monk! We finally broke through to each other universes! That's a relief....
The reason I was picking you up on the conjecture about indigenous labour was not for the purposes of empty point scoring. I do know something about very early mining practices - thousands of years back - and the attitude of the miners and the smiths to how the metals and minerals were mined was not one of the 'raping it' for all they could get (as has so much been the case in recent times). Instead, there was a feeling of working with the Earth who, as the mother, had gestated these minerals and metals within her 'womb'. So it was all carried out with the greatest of respect for 'her' and, because of this, there was a lot of attendant ceremony, rite and ritual around it for the miners to ask 'her' if it was OK to take it.
So this is very different mindset to how we see the earth today - although there has been, since the Sixties, a bit of a swing back in the other direction. But what I'm trying to get at here is that we all can fall into the trap of judging other civilsations way back in the past through the prism of our own modern mindset And all of us come from very recently imperialistic backgrounds. The reason we have the luxury of sitting here umming and ahing about the past with one another, while others can barely scratch a living, is bcause our forefathers went out and raped other countries - and even now, the US president is cynically exploiting the idea of 'terrorism' to take the oil from Iraq.
So my point is, just because all we've known is exploitative wars of one kind or another for the past several thousand years, it doesn't mean that it was always that way. There may not have been the means, for one thing- the intelligence and the speed of communication and transport - during the most ancient of times. And secondly, as I said, there was a very different, co-operative and symbiotic attitude towards the earth, the smallest remnants of which can only been seen today in perhaps, how the Native Americans lived before Columbus showed up.
