I do not agree with you on this.
I do not know what you mean by "moving advantages back and forth between races".
That does not reflect reality as I see it.
This article deals with race in the US. It does not deal with borders.
In the Dominican Republic, race is not mentioned on any legal document, although the official ID card, the Cédula, does have a full color photo.
In the DR, race is not seen as a political thing. There is no such thing as the "Black Vote", the "White Vote" or the""Mulatto Vote" It is something like eye color in the US, except for the fact that there are a lot of illegal Haitians in the DR, most of them darker than most Dominicans.
You do not hear any politicians or citizens talking about how they plan to benefit this group more or that group more. They do discuss regions, though, as some provinces are much more wealthy than others. This is because they are closer to the capital and/or have better tourist sites.
