I agree with you that (especially male) people tend to minimize their (especially female) spouses' interests and accomplishments, and there are hints of that here where LW questions how much the fellowship will help his wife's career—he uses the words "slightly" twice. But taken as a whole, I don't see LW as entitled because:
(a) LW appears to be genuinely concerned for his kids, not his own selfish interests;
(b) LW recognizes his need for an outside perspective and, I believe, is earnestly seeking one by writing to an advice columnist.
