And I'm thinking specifically of my past life, pre-diagnosis, earning enough to buy a lovely 3-bed house with a large garden and in a nice enough area, with no worries about your handbag getting robbed while you push your DC on the swing. No worries about bills, no problem running a car, could ring for a takeaway when we wanted one, had UK holidays, blah blah blah.
When my Ex was here and earning £16k, after 17 years in his trade, it was totally different. Even with Tax Credits.
No holidays, no nice house, lived in an area you can't leave your DC's bikes locked in the shed without them getting stolen, parks a no go area, open drug taking around my DC's, regular stabbings, not able to pay all the bills, the list goes on and on.
In the same town, an income of £45k 9 years ago bought far far more opportunities for a better life than £16k+Tax Credits did 18 months ago.
If you compare like with like, two families of 4 living in the same town, their BASIC living expenses must be the same. I would hazard a guess at £22kpa here.
Anything that comes into their household over and above £22k becomes by definition, disposable income. To do with what you choose.
If your household income is less than £22k in this town, for a family of 4, including all state top ups, then you are in poverty and have no disposable income, and are actually not able to cover your basic living costs.
If your household income is £22k, in this town, for a family of four, then while you do not have any disposable income, you are not in poverty either.
If your household income is £32k in this town, for a family of 4, then you have £10k disposable income.
If your household income is £42k in this town, for a family of 4, then you have £20k disposable income.
If your household income is £52k, in this town, for a family of 4, then you have £30k disposable income.
If your household income is £60k, in this town, for a family of 4, then you have £40k disposable income.
Having £40k disposable income is more than double what some people have total income. If that doesn't make you wealthy, then you need to reexamine your priorities.
If you have chosen to use that £40k disposable income to buy a nicer house, and to run a car, it still doesn't leave you in the position of the family of 4 who haven't even got enough coming in to cover their BASIC living expenses. It just doesn't. And to say that it does is VERY insulting.
If you can't see that, then you are very crass.
