Bouirdic - you are just that couple of years older than me. Even those two years can make a difference.
One reason I chose to work in the Public sector was because they offered equal pay and pensions to women. There were still factories 'oop north' which quite openly advertised wages as "Men £xxx, Women £xxx - yy". It infuriated me, and I was really glad to see the equal pay legislation come in in the mid 70s. It still happened that women clustered in the lower grade jobs, and that men appeared to get the promotions more easily, but it wasn't so blatant.
Houses in the north could be bought for £3,000 in 1975 - in the south east the equivalents were already £8,000. Outside London, public sector salaries were the same so the ability to purchase a house depended very much on where you lived. I saved for a number of years with a building society, and they just didn't want to know when the time came to actually apply I don't know whether it was sex discrimination or what. I eventually got a mortgage via the Local Authority. DH at the same time in the South East had the greatest of difficulty getting a mortgage at all because of the price differential, and lack of similar housing stock i.e. not nearly so many rows of small terraces which made good starter homes.
The married woman's stamp was abolished after April 1977, so I just missed that and am glad. I get a full pension because although I had some gaps in my record, the amount to make up wasn't great, so I paid up. Then they changed the law, to make you eligible after 30 years, so I needed have bothered! I didn't, as I said, get my pension at 60 because they had started increasing the age at which you could draw it, and in England they sneaked the age at which you could get your bus pass up at the same time. I don't remember a word of publicity about that.
I had short foreign holidays and ran an old car, in the seventies but then I consciously went without other things - I didn't drink for example so saved money that way.
Weddings were much more low key. We certainly didn't have the stag and hen parties that happen now - a meal out in the pub with your friends was about the norm.
I am not sure that your work pension will increase this year. DH has just had a letter saying that "Public service pensions [such as his] are increased in line with the increase in the Consumer Price Index (CPI) in the twelve months to September of the previous year. At September 2015 the CPI was minus 0.1%, and therefore there will be no pension increase in April 2016, nor will there be any reduction to your pension." My pension provider hasn't bothered to write yet, but I expect the same. At the same time, this year our Council tax has increased, Water charges have increased, train fares have increased, so it doesn't feel like minus inflation.
I agree entirely with the last part of your post.
