I have never understood the narrative that having family members determine rank, housing and wages of other family member is some sort of miscarriage of justice. Why H is spun as being some sort of exception is a complete mystery given his entire extended family are subject to the exact same rules as he was.
Furthermore, H attended school with plenty of other aristo “spares” who were figuring out their lives with the understanding that they too were not going to inherit an estate. UK aristos either work for siblings who would determine housing and wages or strike out on their own. Most, however, do so without trashing their family of origin.
An obvious example is Prince Richard, current Duke of Gloucester, who the child of a “spare” and also a “spare” himself. He opted out of being a working royal and began a career in architecture. Tragically, his older brother died in a plane crash and R chose to give up his career as an architect and went on to serve his aunt and now his cousin as a working royal.
And it is not just UK aristos. Perhaps H can ask his new Nigerian "in-laws" how inheritance is determined there. In Yoruba culture, the eldest male child, or Dawodu, automatically assumes control, management, and trusteeship of their deceased father’s estate. Sound familiar? Or Igbo culture which follows a patrilineal system where only male children can inherit, with the first son (called the “Okpala”) receiving the lion's share as the new family head. Or Hausa-Fulani culture where family law follows Sharia.
