Bills could easily be £1900. Electric, water, council tax, phones, oil, gas, health insurance, savings, food, car repayment, lunches, fuel, transport, nursery, there are loads of things. Then stuff like gym, dentist, presents, dry cleaning, holidays, days out, pets, charitable donations, god the list is endless surely
It's interesting what people consider as essential outgoings. If and when your earnings drop, you realign this. You don't need health insurance, savings, gym, presents, dry cleaning, holidays, days out, pets or charitable donations.
If you need a car, you might well have to sell on the expensive one and buy an old banger. And yes, it will break down more and cost more to run in the long run, but it won't require expensive monthly payments. Which is how people who are poor stay poor. Lunches, well you need them but you can make packed lunches. Dentist - well you would hope they'd be listed as essential but when the budget gets tight you can do without - just look at the DIY dentistry kits in pharmacies.
It's really weird how some people are so disconnected and sheltered from this. You might think you need a gym membership for health reasons but if you're scraping money together for food, you'll just go for a bloody walk. Or not, you know, what with the other concerns and stresses affecting your health. And yes, you might need a good, reliable car. But you won't get one if you can't afford it.
Sometimes Mumsnet reeks of middle class entitlement.
