What an extremely bigoted thing to say. Most of the worlds indigenous people don’t “live in huts like cavemen”. Where they do have poor living conditions, these are usually a product of external colonization and/or forced migrations leaving them in lands hostile to human life. You realize there are still over 6 million indigenous people in the US, right? Almost 500 million worldwide.

Yeah, shrinking the population would totally help, if we shrank the population starting at the top.
