I think that we are in for a very, very unpleasant couple of decades with ugly inter-generational angst.
The current generation of baby boomers, many (though not all - we should not forget that!) of whom are retiring - or, let's face it, retired about 10 years ago (like my stepmother and my father) on good pensions, look set to live into their 80s, if not longer.
While they live well, several generations of "new" pensioners will retire on worse terms, at the same time as conditions for the younger workforce are reduced.
When the boomers die (as someone has already observed) everyone will be in as bad a state as everyone else (barring the rich, of course, who have always been protected), and things will simmer down.
The irony is, of course, that the wealth of the boomers is, I imagine, unlikely to be passed down wholesale, as much of it will go (rightly) to fund their care when infirm (e.g. my dad will sell up his house, etc., to pay for care, should he need it).
History will therefore record the prosperity of the boomers as an anomaly, rather than a new stage of cultural history in the UK.
