How?
We haven't left the country in a decade. Holidays are visiting family or friends (yes, we reciprocate) or camping in the UK.
I only buy myself new clothes if I need them, never because I just want them, or because it's a "new season". We shop in cheap shops - when I needed a pair of trainers suitable for wearing with dresses I got them for £14 from Sainsbury's.
A takeaway or a restaurant is a treat, something we don't do often.
Our car is currently off the road, and will remain so until we have the money to repair it.
I really didn't think I would be living like this in middle age.
The real issues here are political - childcare and mortgage payments are high because of government decisions over the years. And we've had over a decade of austerity.
Austerity was a political decision, not a necessity, and we're all worse off because of it.
In many other European countries, childcare is subsidised. It should be here, too, we really should be demanding this. (The 15 hours "free" childcare is a fuck up, it doesn't do what it says on the tin.)
Housing costs are ridiculously high in the UK as Thatcher allowed council housing to be sold off, while expressly forbidding local councils from reinvesting the money in new housing stock. And then every government since, of every party, has failed to address the issue of the need for a programme of building modern social housing.
I have a small hope Labour might do something about housing, zero chance the Tories will, and austerity was a Tory policy. Please join me in voting those fuckers out!
