It is, if you stop to think about it, a little silly to argue that the success of Asians means there's no meaningful disadvantages to being African American.
Honestly, the failure to address that concern is one of the big reasons why nationalist and populist arguments are so persuasive.
Are you thinking of the term "WASP" in place of "white"? Italians and Greeks are 'W' but not 'ASP', and Irish are 'WAS' but not 'P' — but I think all three would be considered 'white' by people all around the world and I don't think that has changed.
Perhaps where you live where's a different capital 'W' version of 'White' (contrasted to 'white'), but that's not how most of the world looks at these groups. Do you think the people living Italy, Greece, and Ireland believe they are excluded from being 'white'?
For sure some of them are not white. Not that we should care much, unless we are dermatologists or something like that I guess.
"whiteness" has changed
Yes, the meaning of "whiteness" has evolved -- for sinister political reasons: equating "whiteness" with "successful" serves no useful purpose, other than covering up inconvenient facts like immigrants/Asians doing extremely well, which doesn't fit the left's convenient narratives. Twisting the meaning of "whiteness" really is an incendiary political mobilisation strategy, and you know it. It is a well-worn strategy of political mobilisation going back -- like almost everything on the contemporary political left -- to Lenin. I recommend you reflect on this moral failure of yours: Why not use something like "successful" instead of "white" from now on, otherwise you will continue to be part of the problem. In order to solve a problem, one needs a clear understanding of what causes the problem in the first place.
