The Temptest in the Wilderness

Ronald Takaki’s thesis of The Tempest` in the Wilderness in the book The racialization of Savegery is that the Irish and the Indians were discriminated against for their race and their civilization by the English.
The English have been said to be the founders of the new land. In school they say that the English and the Indians were great friends and got along nicely. This is all wrong though. The English were nice at first until they learned of the resources the Indians had and where they were located. After intruding on the Indians land, the English became greedy wanting more and more. This caused problems because the English were willing to kill all the Indians and/or make them their slaves. One of their main resources the English wanted was the Indians tobacco which then resulted in a huge massacre between the them. Like the Indians the Irish went through these gruesome acts by the English because the English said that the Irish lived outside of their civilization. The English colonists established laws, “Every Irishman shall be forbidden to wear English apparel or weapon upon pain of death. That no Irishman, born of Irish race and brought up Irish, shall purchase land, bear office, be chosen of any jury or admitted witness in any real or personal action” Takaki says in his chapter The Tempest` in the Wilderness.
My question for the argument is, why shouldn’t the English be greedy and take what they can? If they did not take is over they may have been killed by the Indians and got nothing. They could have risked their life by the trusting them then being turned on by the Indians. Personally I agree with the author’s opinion and that the English should not have done what they did. I think the author’s opinion gives a strong impact on his argument and makes some solid points to show his side.
While reading this I wonder why all this is not told to us when we are younger. How come we only hear of the good and never the bad? It disturbs me the way this land was found but that is how the world is today as well. Not as extreme where everyone is killing each other but people get what they want some way or another. These wants turn into war and that is how the killing occurs. I wish racism did not exist but it is part of life and the world is going to have to deal with it.
