So do laws function at a macro level? Does a society have an obligation to follow it's own rules at a macro level or not?
That’s subjective and up to you to decide on your own based on your own moral code.

I am trying to point out to you that cultural progression has never and will never respect the boundaries of a substandard culture for any length of time. It is not a matter of whether this is good or bad, as it is simply a natural occurrence.

And example..

A Nike factory is built in Africa. Are the corporate execs making a conscious decision to ruin the native culture of the area, or are they thinking about the best way to run their company? Now the Africans start to wear Nike clothes they are given at the factory instead of the traditional dress and now they are forced to work in the factory to keep up economic status with all the others. In that tiny microcosm, a culture was lost. There was no malice toward the Africans by the Nike corporation, they simply didn’t have a society strong enough to resist the benefits of working at the factory and the negatives of not working at the factory. Its simple progression.

This is what happened on a much larger scale all around the world. Native cultures simply were not able to compete with that of Europe. Was it wrong to break treaties and such, of course, but im talking about the much larger culture wars that were fought all over the world, and have been since the mankind has existed. The broken treaties and even the genocides were simply results of two cultures competing.

In an atmosphere where cultures have been allowed to grow so separately, the results when they meet are often violent. Today, in a much more globalized world, cultural progression is much more subtle, but very much the same.

It really does not matter if specific treaties, laws, or morals were respected or ignored; the native cultures and way of life could not compete and ceased to exist. This is a natural occurrence.

That is why I am against all of this talk of reparations and the guilt trip modern day "natives" try and push. They are essentially advocating the end of cultural progression, which has been nothing but a positive for the human race as a whole. To bring economics into it again, the world operates on a form of "cultural capitalism". Those cultures which are strong relative to the others survive and grow while those that cannot compete on any measure of standards fail. There is no reason to compensate the relatives of a failed people.

I don’t know about the natives around your part of the world, but over here they never even came up with the wheel. They were destined for the cultural trash heap. I say - get over it. Its been centuries..
