Late to the party on this thread....
I am not a baby boomer, but also think people these days don't like saving and living frugally. I know my parents did. They were home owners, but also mended everything including socks to nake things last.
I mend things (quite enjoy it actually), but this kind of stuff completely overlooks the completely different economy we now live in. Material goods (esp clothes) have dropped in price relative to wages, because of globalisation; other goods and services have massively increased. In the 60s and 70s socks were more expensive than thread/wool; now if I want to mend my socks, buying the thread costs more than a new sock does. Apart from a desire to save things from landfill, you have to admit that it isn't "thrifty" to mend things if a new one costs less than the mending?
Same these days for loads of stuff from electronics to food. In the 60s it was cheaper to make your own clothes/knit; now the wool costs several times more than a cheap jumper. It costs me twice as much to make a Christmas pudding even with Basics ingredients than buying one. Buying ready meals or imported cheap food flown in by a big supermarket chain from Spain or New Zealand is far cheaper than locally-grown produce. And who these days would mend a television when the labour cost of having it done is more than buying a new one?
Importing goods from Asia, technological change, built-in obsolescence, high labour costs - all of these things are very different from a few decades ago. Pretending that it's cheaper to make do and mend and make vegetable stew from scratch is a kind of economy that disappeared decades ago along with the historic mean for house prices.
It's just really dim not to recognise that saving money today isn't at all the same as in the past, and that the changes in house prices compared to wages are real and supported by lots of data. But then the people who argue all this "it was worse in the 1970s" stuff don't want to see the data either. On previous threads like this I took to posting a long Office of National Statistics report on intergenerational spending patterns which very clearly shows that the vast majority of consumer and "luxury" spending is - surprise surprise - actually by Boomers, from holidays to clothes to restaurants to food to technology to cars. But this doesn't fit with the narrative about how decadent younger people are and how virtuous the Boomers are - so every time I have posted this the only response is total denial of the "oh well statistics are all faked and manipulated" kind. Which just shows you what a mindset we're dealing with (and why that generation voted for Brexit despite every logical economic argument against it).
