Just a couple of points.
I am sure you have researched the incredible interest rate on mortgages in the seventies and eighties, pretty high weren’t they?
I am equally sure that you were shocked to discover that in the sixties , seventies and through part of the eighties it was very hard for single women to get credit, be it for a mortgage, car loan or new washing machine unless she had a male guarantor, didn’t matter who he was or even if he earned less than her, the important thing was he had a penis.
I expect you also discovered that in the seventies only 15 to 19% of young people went into further education, now the figure is above 50%. Most people left school at sixteen, many into low paid manual , clerical,or administrative work. Even “professional” jobs such as teaching, nursing and the police were very low paid. (I was actually financially better off in my last year of University than I was in my first three years of teaching)
I am almost sure you will have looked at womens pay pre the equal pay legislation, and the lack of maternity rights and been shocked not only at the pay gap but at the almost complete absence of maternity rights for working women.
You may looks back on a golden age for baby boomers, and yes for some it was a never to be repeated perfect storm of post war full employment , a very new welfare state that hadn’t been thought through economically from the start, a push to get a better educated workforce, Labour governments, and more generous public housing provision which meant less pressure on private sector housing markets which were therefore kept stable and more accessible.
Also remember that most people didn’t have cars, many didn’t have phones, outside toilets and no bathrooms were common, peoples expectations about holidays, televisions, domestic white goods, eating out, entertainment, smart clothing, home furnishings and decor etc were completely different.
Some things might get worse in the future, but for most people under 50 today they are already a damn sight better than they were in the past for the same age cohort.
