YouDoTheMath, let's do the Math! 
The minimum we need to live on is this:
£685 accommodation (cheap for here, we live in a shithole, but at least we have enough bedrooms in this one for DCs)
£140 council (roughly - might be out by a tenner or so these days)
£50 petrol commuting for DH (needed - no public transport/cycle option)
£48 bus pass for me (4 buses each day
)
10 work clothes, gotta put something in there even though we barely buy anything
£200 food for 3 DCs and 2 adults
there you go. That works out to £1133/month, which needs an income of £1416.25 a month before tax.
Now let's add in a few other requirements - not optional.
100 car insurance (needs to be insured for work too since he's on call every third weekend)
£5 MOT kitty
£50 car repairs/service, based on last year's total yearly bill split up
£10 kitty for school uniforms spread through the year.
£10 kitty for school trips spread through the year.
£10 house insurance (this might be higher, can't recall)
£15 gas.
£50 electric.
Now we're at £1383/month, which needs an income of £1728.75 a month before tax.
That's £20745 a year salary, minimum. Which is a great salary for around here.
Then let's consider dentist bills, glasses, haircuts, stationary for their homework, home repairs, and other semi-optional items like life insurance or a Christmas kitty.
You could easily add on a few grand for that each year.
And this is only living to the most basic standard of living, subsistence living, what I've described above. It doesn't include a telephone line or call costs, it doesn't include money for a computer for the DCs to use, no cash for buying them a bike to cycle to school with (to save on the need for petrol outlay), there's no money there for a meal once a year. The food bill is also quite lean, but that's because I do a lot of batch cooking and I've had years of practice.
Then consider the childcare costs most families have, which can easily swallow another person's fulltime wage even if they earn a decent income.
There's no way you can support a family on the minimum wage, or even a "semi decent" wage these days.
Is it any wonder there is such a thing as working poor in this country? no wonder so many people are considered "rich" enough to earn too much for ANY help but feel like they're getting fucked from every angle.
It does put things into perspective a little, eh?
