You're pretty judgemental about a people who have been living on these rivers for 9000 years. Did you ever really try to get to know any of them? I've known plenty and none of them ever got big chunks of cash when they reached any age. You say you don't like how their arrangment affects you. What about how you affect them? Does that matter? Think outside the box that defines your lily white life. Put yourself in their shoes. You might find you have quite a bit in common with them.
