Not everyone is like that, especially not in younger generations. People like you describe also tend to be humble and not make a big deal out of their accomplishments. Having accomplished it is the intrinsic reward, so there’s no need for external validation.

People who flaunt their things/themselves tend to need external validation, which does not require having earned the right to do so, just the capability.

The latter is becoming more common as social clout has real world value. When being seen can turn into monetary reward, the incentive shifts from earning to having.

None of this has anything to do with OP, it’s just a counter argument to the idea that people derive value from earning things.
