There Goes the Neighborhood

The Native Americans were completely bewildered when the explorers came. They were wildly disadvantaged in economic, environmental and educational advances, which made them an easy target for the Europeans. They were manipulated and they didn't even know it was happening until it was too late. They also had values which enforced trust and hospitality, which contradicted the settlers, who only cared about money and power. This meant that the natives' attitudes were positive towards the newcomers and were hopeful that they could provide new resources as opposed to regarding them as potential threats. The explorers also used cultural indoctrination to force the natives to adopt their principles.
This situation is similar to modern day adoption. I know, it sounds a little far off, but the concept is the same, just not sinister. Children are taken from their birth parents (who do give consent) and are given a new life with a new family. Often these children come from third world countries who don't hold the modern values of society that we hold. I think that it is a great thing for children who would otherwise not have a good life in their old community, but it has its downsides. A lot of these kids grow up with no idea of their heritage or culture, and since they're brought up by a different family and a different society, are essentially made to conform to that society's standards. These children don't have a choice where they go, and I'm not saying that they should considering that they're usually very young when put up for adoption, but that choice is made for them regardless. The two things are even more similar when it comes to illegal adoptions. Those children's parents don't choose for them to be given to a new family, and often spend their lives trying to find them.
