I am a retired boomer myself, but it does irritate me when some of my generation imply that they are only better off than younger people, because they worked hard for what they've got.
I'm not disputing that they did very likely work hard, but working hard nowadays doesn't guarantee the same advantages it did then, crazy house prices particularly in London and the SE, being just one example. Even taking into account the very high interest rates at some points in the past, housing was generally much more affordable, and of course we had no student loans to pay off.
As for 'higher expectations' than in the past, well, unless it's the dafter kind of extravagance, I think that's a normal generational thing. My mother (born 1918) took it more or less for granted when we were small that she'd have a washing machine (not automatic), a vacuum cleaner, and a phone, none of which her own mother with 5 children had for many years.
My great-granny, who had 10 children, all of whom survived, and was not really poor by Victorian standards, didn't even have a pram.
My granny who had the 5 children once told me she'd asked her once how on earth she'd managed without one.
'I used my arms.'
