Are we talking disposable income here or average incomes? Have they looked at the incomes across families or across the spectrum in general?
Disposable income will possibly be greater for pensioners because many will have paid off their mortgages, will not have the outgoings involved in going out to work, children (what is the average cost of bringing up a child these days?) etc.
So, relatively speaking, a pensioner couple with an income of £27,600 will feel better off and be able to afford more luxuries than the same couple bringing up children, travelling to work etc.
Our joint income is not as much as that of any of our children, not all of whom are millennials, a couple of them are slightly older. They struggled at first, as we did, but none of us thought that we should start at the top of the tree, or even halfway up for that matter.
I agree that there may be some very wealthy pensioners out there and I am wondering if they took the value of houses into account too as some houses in the SE in particular are very valuable - and unaffordable for most millennials although I do know more than one or two who are buying in the region. But it is a paper value unless you want to move or are able to downsize.
