Because the status quo throughout history is an extremely small number of people getting the most benefits by far and everyone else getting screwed, and everyone seeing this as normal. People are used to it, while having everyone on relatively equal footing is new and therefore scary.
Teddy Roosevelt never said “The only good indian is a dead indian.” That quote is typically associated with Philip Sheridan.
A number of sources claim a similar quote (“I don’t go so far as to think that the only good Indians are the dead Indians, but I believe nine out of every 10 are…") alleged to be from an 1886 speech in New York, but this still goes against how he treated native americans generally and I can’t find the original speech so I’m a bit suspicious of this as well.
