The Gilded Age?
The Victorian Era?
When was the golden age of noblesse oblige-driven egalitarianism?
But if you want to claim that people who reached their position via "meritocracy" feel less noblesse oblige, I want to see evidence.
So far I've seen no evidence of this.
If we don't insist on evidence, people will decide which theories to believe based on their prejudices.
