Indian Americans, Japanese Americans, Korean Americans, and Persian Americans (the last classified as “white”) all have income levels exceeding those of whites. I believe that among European Americans (excluding Jews, who cut across national boundaries) Greek Americans happen to have the highest per capita income. Its been over a decade since I’ve looked at income by ethnicity in my sociology class, but I wouldn’t be surprised if the figures were the same.
Here’s some data on all this:

one has to wonder to be candid, since they do so well here why are the cultures they come from so messed up except for Japan?
there is a lot of disparity between various Asian groups too..
