Bias goes both ways and biases effecting social status for Asians are typically positive. For example, if hiring for a Mathematician from three resumes, 1 White, 1 Black, and 1 Asian and being unaware of actual skill, the Asian would likely be considered first. In this case bias helped the Asian get a job that will raise their social status.
There are negative biases towards Asians as well, but they don't have much effect on social status, such as being bad drivers.
There are also positive biases towards Blacks, but the those positive biases don't have much effect on social status. An example would be if basketball team had to be constructed from a pool of available players, again unaware of actual skill, the Black players would likely be picked first.
I think the real point is that bias does have an effect on social status. Depending on what those biases are it could be a positive or negative effect.
