What do traders and NGO’S do for these cultures?

Traders intentions are usually just one thing, to make money to do whatever they have to do to make it and not worry about others around them. They are usually ahead on the times and have good equipment for their business and to make themselves look better and make people want to do business with them. When it comes to farming that was up to the tribe people they were in charge of who would farm where, on what piece of land, and how they were going to go about doing it. Then the traders come in and take over pretty much ruining all that they had been working for and pretty much turning them into slaves making them work for the traders profit which devastated a lot of the small farmers profits.
When it comes to the Sawi people and traders entering their lands, I think the traders wouldn’t have a clue as to what they were entering into and not do much to the Sawi tribe because they would just do what they always do. Fatten them and then eat them, become good friends and betray them without any questions. They would treat the trades just like the do everyone else and the traders wouldn’t know what was going on they probably think that they are out witting the Sawi people because they are giving them food and being friendly to them. I could be totally off with this thought they might outsmart the Sawi tribe and end up doing the same thing they do to most tribes.
