If one is to create a more just universe, then they ought to know that equality is not easily defined - should equality be their concern. If one is of a specific group and they wish to live more equitably, more justly, it is certainly correct that they ought to have opportunity, but it is not always the case that more power or wealth will present more opportunity and merely taking more status or influence for oneself is in no certain way better or more just. Just as equality in an absolute way - equality in every aspect of life - is not equal, so is more power not more justice. And the blind thought that "giving me more influence or potency" is actual justice is flawed, though more wealth and influence often accompany the expansion of justice.
Justice is a thing measured by contingency and power, but an equal measure does not mean equality in all things.
