It is wrong because people are being underpaid for not participating in silly upper class rituals that are not relevant to productivity.

There are a few industries in the UK were you’d be better off being a foreigner than a lower class local.

The ideal situation is one where people are judged by the value of their work and not by the socioeconomic background of their parents.
