In one of the best scenes in one of the greatest comedy series—Yes, Minister—Sir Desmond Glazebrook explains to Sir Humphrey Appleby that, yes, he does carry a copy of the Financial Times with him. But that doesn’t mean that he actually understands it.
(In case it's not clear, the Financial Times is read by the people who own the country.)
Fortunately, the 404 error page of the Financial Times is far more comprehensible to those of us with a passing familiarity with economics. Or, if you’re like me, just smile and laugh when you see other people around you doing likewise. It will be less awkward.
