When thinking about the meaning of this document, keep in
mind what the question in.  The question was about the social and economic impacts of
the flow of silver worldwide.  This document has to do with the social impact of the
worldwide silver flows on Native Americans in the Spanish
colonies.

The document is written by a Spanish priest, who
might be expected to care about the welfare of the Indians who worked the silver mines. 
He is pointing out how hard the Indians are being forced to work in order to extract the
silver that gets shipped off to other parts of the world.  This document shows that the
shipment of silver all over the world had major impacts on the lives of various people. 
In this case, it meant that these men had to toil away, carrying heavy bags of silver
ore up ropes out of the mines.

So, this document is meant
to make you address the social impact of the silver flows on those who lived where the
silver mines were.
