You completely missed the parent point. American consumption might be 10 times the Indian per capita, but there are way more Indians than Americans, and soon there will be more Congolese and Nigerians and other Africans, and while American consumption is going down, African and Asian consumption is going up. If both USA and EU disappeared today, it would only reduce global emissions by 25%, and that fraction will go down as African and Asian emissions grow. If USA cut its emissions in half, it would reduce global emissions by something like 7%. So yes, we can try to reduce our consumption, but it won't really change a thing in grand scheme of things.
