Been havering about adding my bit here - in the interests of harmony I will suppress my more emotional reactions and try and stick to facts...
OK, I consider myself to be fairly frugal and good at managing money. I know that our core, essential expenditure (food, bills, transport costs, mortgage etc) is around £1600 per month for 2 adults and one toddler. If we actually had this little coming in I know we would find it tough (but possible) so I think anyone successfully coping on less than this is a) doing really well and b) having to work pretty hard at it.
Our income is actually considerably higher than this which means we can afford savings for holidays (£150 per month), cleaner (£60 per month), weekends away, meals out and entertainment, toys for ds and ourselves, clothes for ourselves (£150 per month each for clothes and other personal expenditure), savings for the next car (£150 per month), house and garden improvements including new furniture etc (£200 per month) longer term investments and savings (quite a lot), books, newspapers etc etc.
I've always found the problem with budgeting is that when you count up what you think you spend, it seems as though you should have lots left over, when actually you don't (!) - the black hole inevitably being all those little (and not so little) things you forget about (haircuts, sandwiches, chocolate, magazines, presents, car repairs and servicing, etc).
I can't agree that 'we are all in the same boat really'. Sure, everyone has issues about balancing money and time, but there is a world of difference between a monthly income of £800 and one of £8000 (well, £7200 to be exact!). Don't get me wrong, I don't begrudge the hot shot city earners - I have plenty of university friends who went down that route and I certainly would not swap their lifestyle for mine. And anyway with a net income which places us comfortably in the top 10% of household income (last time I read the figures anyway), we are most certainly 'rich'.
