There is a huge chasm of lifestyle 'choice' though, isn't there? Often on MN you see higher rate tax payers who include in their essentials 'private education' 'pedicures, manicures, hair', 'wadrobe capsules', 'children's sports, music and drama clubs' etc. For many, many lower rate earners who rely on tax credits to allow them to survive, they include in their 'essentials' 'at least one meal that contains meat each week' 'one pair of shoes which does not have holes'.
DH and I are 'low income'. DH earns £11k per year, I get carers allowance for DD1 and we have two younger children also. I am a SAHM out of necessity, right now. I consider us to be doing ok, and in fact, we also help out my Mum and Dad who are on an even lower income. But, to consider us to be 'doing ok', I've realised that:
-I never have my hair cut (well...I remember having it done last summer, I think)
-I never have any beauty treatments of any sort.
-I can't remember the last time I bought clothing of any sort - I just use what I was wearing last year at this time, which happens to be the same thing I wore the year before that, and the year before that.
-DH and I don't go out. Ever. The last time we went out was for our anniversary the year before last.
-DH and I don't drink (DH will have an ale with a Sunday Roast, I guess, smoke or indulge in any other luxuries.
-Our children don't do any activities which cost money.
So if you are a high rate earner and your money is a bit short after your 'essentials' that isn't necessarily the same thing as someone on a low income who says that their money is a bit short, because for them, they are probably already buying the basics range of food, walking when they can, etc., so there is no belt to tighten.
