The thoughts of someone who thinks "Western society" is where it is by being conscientious of how they consume and preserve resources for future generations, and is apparently unaware of "Western society" eating other societies' marshmallows.

Another option is they are intentionally ignoring "Western society" consuming other society's marshmallows to make them seem more deserving of their spoils, and others more deserving of their lack of spoils.

No, even countries where exploitative multinationals contribute an insignificant portion to the economy can be prosperous if and only if they have low levels of corruption. Even if they have no natural resources, they still have people who can produce value that can be exported. But only if government officials don't steal all of it first. In a lot of places you can't start a company of any kind without paying tons of bribes.
