Except that this is also an argument that has been demonstrated to be false; that people on £60k struggle because of choices or different ideas about needs the "nice house" argument. However it was demonstrated how someone on a £13.5k income had a choice over housing also and the factor is likely to be dependents on the income, housing costs, number of people with income in the household etc rather than strictly the place within the income distribution. Unless, and some people have said, they don't believe people on £60k before tax can possibly be living frugally out of necessity. Really those beliefs have not been substantiated by anything greater than it being what those people think based on what they earn and how far it goes for them and I think this shows they don't really understand the extremely complex nuances within the system.
All I've ever tried to say is that someone's real actual income is not the same as their pre tax income in the distribution and you can't actually tell how wealthy someone is or how secure based on that income.
All kinds of things have an impact on your real income/security including tax credits, childcare help, childcare vouchers, dependents, debts, benefits in kind from the state or employment, how many of you in the house work, housing, travel/work related costs, assets, the state of repair your property is in etc. £60k might be high in the distribution but it does not bring you above being affected for better or worse by any of these things. That's why it is factually accurate to say it is a high pre tax income by distribution, although maybe not huge which would be relative to the top income, but it isn't factually accurate to talk about gardeners, cleaners, school fees and choices.
The argument about choices CAN be applied across the board for the vast majority of people and actually families with medium level incomes can be much worse off than those on low incomes, single people on low incomes can be better off than large families on a high (in terms of distribution) income, single people on benefits or very low wages are worst off of all working age fit to work nationals and asylum seekers, carers, the disabled, terminally ill and mentally ill at the moment can be worst of all as they are most likely to fall between the new gaps in entitlement. It is really complicated. A lot of it isn't even about poverty, what it is about is struggling.
I just think people should remember everyone is an individual with individual circumstances and fine, treat any claim you like with scepticism but try to listen objectively too instead of getting carried away with telling people that they have xyz and should do xyz. That applies to people labelled scroungers as well as people labelled as being on "huge" incomes.
