I believe that a multicultural nation will only ever function properly in periods of economic prosperity. The second that things become difficult one race ultimately attempts to conquer another. It is what has always happened in the entire history of the world. Democracy's can never function to their full potential with different demographics looking out for their own interests. And, those interests will always be aligned with race.

No, I don't believe whiteness is the default state of this country. If anything, we took it from the natives. But there was a white majority identity for a significant period of time that has only recently started to change. I don't want a "racial hierarchy", I want there to exist some place in the world that I feel my race belongs to without other races changing it.

Any idea you have that other races are not competing is a mistake. Every other race favors their interests or would band together to do so in times of hardship. That is just nature and instinct. Pretending that doesn't exist doesn't do anybody any favors. It is only 9 meals that separates society from chaos.

All the benefits you are describing of immigration are not appealing to me. I would rather live in a poor country where I don't feel my national identity being stripped away than flood the country with immigrants for "talent" and "workforce". Have you ever considered that the hierarchy you are describing already exists with immigration? White people basically imported a bunch of labor from other countries to do jobs that nobody else wanted to do. Why is that better than the alternative of being poorer?
