According to the theory of relativity it depends on the observer's frame of reference.
Abstract sense of "time as an indefinite continuous duration" is recorded from late 14c.
Personified since at least 1509 as an aged bald man (but with a forelock) carrying a scythe and an hour-glass.
Having said that, it is certainly true that in other countries, people of color could have power sufficient to discriminate against others, including whites.
Although even anti-white bias in those places is somewhat limited by the reality of global economics and the desire for good relations with the West, it is possible for persons of color in those places to mistreat whites individually and, occasionally, collectively (for instance, the treatment of white farmers in Zimbabwe by the Mugabe government). White privilege refers to any advantage, opportunity, benefit, head start, or general protection from negative societal mistreatment, which persons deemed white will typically enjoy, but which others will generally not enjoy.
The fact of general advantage doesn’t require unanimity of outcomes favoring whites.
In certain situations, other factors will effect the distribution of opportunities: among these, socioeconomic status, sex, gender, sexual orientation, religious identity, age, or physical disability.As a system, racism is an institutional arrangement, maintained by policies, practices and procedures — both formal and informal — in which some persons typically have more or less opportunity than others, and in which such persons receive better or worse treatment than others, because of their respective racial identities.Additionally, institutional racism involves denying persons opportunities, rewards, or various benefits on the basis of race, to which those individuals are otherwise entitled. White supremacy is the operationalized form of racism in the United States and throughout the Western world.At the systemic level, people of color can be racist in theory, but typically not in practice, and certainly not very effectively.Although a person of color in an authority position candiscriminate against a white person, this kind of thing rarely happens because, a) such persons are still statistically rare relative to whites in authority, b) in virtually all cases, there are authorities above those people of color who are white, and who would not stand for such actions, and c) even in cases where a person of color sits atop a power structure (as with President Obama), he is not truly free to do anything to oppress or marginalize white people (even were he so inclined), given his own need to attract white support in order to win election or pass any of his policy agenda.Although I believe all persons are harmed in the long run by racism and racial inequity — and thus, white privilege comes at an immense social cost — it still exists as a daily reality throughout the social, political and economic structure of the United States.
