Just a sidenote:

In the old days, one important reason to go to war was that it was expensive to feed an army. Because armies would live off the land, it made economic sense to have one's army to feed off someone else's land. Also, wars were a convenient way for the younger sons of noble families who would not inherit their fathers to gain a fortune of their own or die trying. The so-called honorable life of the nobility of old (in comparison to the banal life of modern middle-class) was to a large degree about things like threatening to kill some poor peasant's children in some foreign country to get them to tell where their last sacks of grain were hidden.

On the topic:

Yes, attention is the new land, or oil. I suppose we still have something going for us. The day when we ordinary people have nothing to sell will see the beginning us us being quarantined and prepared for extermination.
