I'm a single mum in my 60s. With a business degree, and decades of experience, the most I earned in a year was £75k, outside London, plus a good benefits package (car etc).
I'm moving towards retirement now. I've taken a local job, well within my abilities and earn about £50k.
On that I can pay my mortgage, council tax, half school fees for my ds and generally have a nice life.
What I do not have are: multiple foreign holidays (a week in Portugal last year), gym membership, new cars on PCP, gel nails, facials, spa days, takeaways, expensive hobbies, tattoos, weekly meals out, weight loss drugs, shop-bought lunches, take out coffee, Netflix, Pay TV, the latest phone .....
I think people's expectations have risen and priorities have changed. So much stuff is touted on social media and most of it is completely unnecessary or of little benefit. There are regular posts on here from people with £120k a year who claim to be 'just managing'.
The major necessities now are housing, student debt and childcare. Waiting until late 30s to have a child is becoming the only way. I had ds in my 40s, I was lucky, but it is unfair on those who may miss their chance.
