Judging by the actual toffs I've known sufficiently well, they get taught during their time in Public School as teenagers to separate presentation from their true thinking and desires, i.e. their true identities.

They'll do what they think they can spin as the right thing whilst being seen, but outside that, all bets are of (it really boils down to the kind of person behind the mask).

I think expecting to change their identities through forcing them to wear certain masks is like expecting that repainting the façades of a Potemkin Village will magically make the real buildings appear behind them.
