Last time I checked the 300M people are insignificant compared to the world population, but they use 25% of the energy. And since "we" includes the whole world "we the superior people" are also part of the problem.
Sure "we the superior people" can buy whatever the "we the superior people" want, but not caring about the sustainability rest of the world is.. quite ignorant.
Every nation has their own arguments to justify their action, but no government wants to look an the bigger picture because that is painful. It does require less consumption. It's about everybody and the long term and not only the US. If we're out of resources, we're out of resources. Game over.
