So is the world's total wealth more or less than it was a thousand years ago?
That's sophistry.
This country has the Red Cross handing out food parcels, Save the Children spending money here and foodbanks growing at a massive rate.
A thousand years ago, one might have walked outside and got a few sticks to lay a fire to keep warm and to cook. One might have gone hunting for food or picked fruits and nuts and mushrooms etc.
Try doing that these days – not least in the urban environments in which most people live (having been herded, in effect, into them after enclosure and deforestation, in order to work in industry for the benefit of a limited number of people).
I mentioned in one of the comments I copied over at the top of this thread that the likes of Richer Sounds and John Lewis can treat their workforce decently and still be hugely successful, profitable companies. It is, at base, a moral/ethical decision to decide to do otherwise, although (as has been discussed here before) being listed means that the City applies artificial pressures on businesses (constant growth at rates determined by the City to be acceptable) that put increased pressure on companies to 2stop treating employees as an investment and start seeing them simply as a cost to be cut.
If the wealth – no matter how great – is not shared around more equally than it ever was, and takes account of the cost of living, then it is meaningless to talk of whether the world is wealthier, as a whole, than it was a millennia ago.
