Asians are indisputably higher earners in US than white, on average. If anything it would make more sense that people view it that someone from an Asian country such as my wife married down and not up, if we're viewing through the race lenses you are viewing things through.
This is true but it is not the factored into the subconscious hierarchy. Globally and locally White people are viewed as the top.
Additionally, you should realize that the average income for asians here is highly skewed by a few top earners.

Income inequality among asians is the greatest of any race.
Factoid: the second richest kind of heterosexual household in the US, on average, is Asian woman, white man. Interestingly, Asian-Asian and White-White lag significantly behind both.
Almost paradoxically, from a purely financial outcome perspective a white man is expected to be better off marrying an asian woman, while an asian man is expected to be better off marrying a white woman.
I didn't realize there was a pair like that where both male and female are statistically better off financially marrying the complement, but it seems white/asian pair is the winning combination for maximum expected income?
