I used to work (many years ago, in the early-mid 1970s) in a civil service dept where loads of people retired early on generous index-linked pensions.
Most of those people are probably still alive (in their 70s/80s now), still raking in massive pensions, & there are a lot of them out there.
However, they will all die at some point, won't they? NB I'm not recommending euthanasia for them (much ) but, as that generation gradually stops taking money from the state over the next 10-20 years, that will surely mean that the burden on the rest of us will diminish?
