The Red Power movement as such is not around any more. This is largely because many of the things that it was trying to accomplish are no longer issues among the Native American population. This is not to say that there are no problems among Native Americans, but the majority of things that the Red Power movement was fighting for have been accomplished.
Now, the struggle to improve the lives of Native American centers around different things. It centers around legal battles over tribal recognition. It centers around trying to create casinos. It is no longer focused on trying to get the sorts of basic rights and attention from society at large that the Red Power movement was aiming for.
