Being a teenager in the 00s, the idea of a obtaining a £40k a year job was seen as the aim for most. If you got to that pay grade you were going to be relatively comfortable. Anything more and you were in the money.
Now, it feels like that £40k a year mark is closer in equivalence to £60k/£70k nowadays and wages for most sectors, primarily private, have not increased that much if at all in the last 20 years.
I know fellas in the building trade earning as much now doing carpentry and joinery, roofing etc as they were in the early 00s/mid 00s.
The modern obsession over property ownership and the absolute need for both the husband and wife both needing to work because of it has caused a serious imbalance in my opinion. Everything is viewed as combined income. If your single you are swimming against the tide immensely.
My mother looked after and raised me and my brother for the first few years of our lives in the 90s. My dad struggled but it was doable, and the family bond was and is greater for it. That would in no way be able to occur today, not with the jobs and income they had. You would need at least one person on 100k a year to do that now.
