Was there ever a way for American Indian and white settlers to co-exist… or was it impossible from the start?

According to my history teacher Americans forced the Indians out of there original way of life. This was all because Americans brought different means of life and tried to sell them to the Indians. For eg. Indians get most of there supplies from the buffalo but Americans try to sell the Indians there fancy silk but the Indians use the Buffalo hide to make coats etc. So the Americans killed all the buffalo and took the necessary source of living form the Indians and put it in there stores and the Indians had no American money so they had to work for the white man and get money and buy into the American way of life which eventually ruined there life as it was. OK note if you are talking about Americans before independence they would not me called Americans but British North American settlers and Indians are the same as Amerindians (American Indians)
