AuntJane if you sued to work for the ONS then you'll have enough economic knowledge to be aware that lots of things have dropped in price in real terms over the last 40-50 years and lots of other things have increased massively in price. Whilst salaries have stagnated since the early 2000s (and for some age groups from before then), asset prices have risen massively. Many items that were once "luxuries" are now very cheap in relation to salaries; whilst many items that were once reasonably priced or free (houses, education) are now not at all.
Houses have risen in price more than 3.5 times in real terms since the late-90s, when they were last at historical mean values compared to average salaries. However the cost of foreign travel and electronic items has dropped massively in real terms. But the two things aren't equivalent - when starter homes cost twenty times your salary, and deposits needed in many parts of the country are in the region of £50,000+, so far out of reach that many young poorer working people without wealthy families might as well realistically aspire to flying to the moon, are you really saying that you think the problem is they are choosing to buy a smartphone rather than to PAY FOR YOUR PENSION? Well, what a selfish lot. They are already going without the big things in life, e.g. pensions for themselves, houses, and being able to afford a decent standard of living for their families: but they should THINK OF OTHERS and be going without even the little things in life just to make sure that Aunty Jane gets her winter fuel payment.
It's very disingenuous to suggest that the problem is that people can't afford to pay for OTHERS' pensions (eg. as a collective, when their own salaries are stagnating, to pay for pension entitlements for a demographic bulge generation that dwarf the generations below), because they are buying "luxury items". Perhaps the problem is with a generation that is expecting a free lunch: to have gobbled up all the houses, jobs, healthcare and pension entitlements for themselves, whilst being unwilling to make any sacrifices? The young have to pay three times for houses what their parents did, as well as for education, and to maintain the pensions of those above them so they can keep the expensive houses the younger workers can't afford? Whilst not being able to save into pensions themselves?
Looks increasingly like the "triple lock" is wanting to have all the housing wealth, all the pension wealth, and also all social and healthcare needs paid for, without having to give up any of the aforementioned housing or pension wealth to pay for it.
It's a good thing young people have all these high-paid permanent jobs, that are better paid in real terms than previous generations', to pay for it all....oh.
