It is a known thing that Bilinguals usually have a smaller vocabulary by grade level in both languages on average compared to most peera but well within proficiency windows. Social issues are likely way more "awkwardness" of being a minority among a minority than shared identity than deficiency related. Looking at the numbers effectively it seems that monolinguals have diminished returns - and I can see that just because a lot of problem spaces are like that. Granted "vocabulary size" isn't quite apples to apples given how languages and syntaxes differ.
