In 1989 I flew LHR/HKG/LHR for just under 600GBP (on some sort of super Apex, I guess). 20+ years later you can still buy return tickets for the same money if you book in advance.
In the mid 1990s I used to pay just over 3,000GBP for LHR/HKG/LHR in F for a full fare flexible ticket. Now it's around 9,000GBP.
Maybe it's time for the boys and girls in the back to pay their way
