First of all, y'all are all rich af by the standards of everyone I personally know, so you know... I don't see how any of you guys won't be fine for the rest of your lives. That said, your daughter has gone above and beyond, sacrificing herself to support the entire family, including her brothers (who I do believe are also probably extremely hard-working individuals. Hard to make it through med school if you're not.) Your husband's choice to reward her for her sacrifice and competence seems totally fair. Your sons will be absolutely fine on the "meager" wages of a doctor (not to mention what is probably a fairly sizable inheritance) . Maybe you should all try to instill the attitude of looking out for each other. Considering your family's sizable wealth, it shouldn't be a problem to make sure everyone is well taken care of into their old age. Work together. And let your daughter get what she's earned. YTA.
