I don't think things are "better" or "worse", but they're certainly different.
Affordability of homes is going back to how it was pre 80s. We "peaked" in terms of wealth, luxuries, home ownership, etc in the 90s and 00s but it was all smoke and mirrors and some kind of "correction" was always going to be needed, and that's what we've been going through for the past 10-15 years.
Yes, a couple of older generations massively benefitted from the "easy money" couple of decades, with rising house prices, endowment policy payouts, demutualisation/privatisation windfall profits, etc., and of course oil and gas. Lost of poor/low income people got windfalls from buying their council homes at massive discounts and then selling them on for a huge tax free profit or renting them out.
But, at the same time, the older generation often also had very poor/impoverished upbringings in the 50s, 60s, 70s., i.e. the frost on the inside of your bedroom window was very real, as was not having a family car, not having washing machines, inability to buy a house because they ignored the wife's wage for mortgages, etc. A lot of such people went from a relatively impoverished childhood to a pretty good standard of living, wealth, etc., for no reason other than being born at the right time and being lucky.
As for the "can't afford it because of coffee" matter, it's not just one thing. I look at my son's bank statements and weep - he is at Uni, but manages to spend a few hundred per month on what I'd consider non essentials such as Netflix, a completely unnecessary expensive phone contract, takeaways, xbox subs, and several other online subscriptions.
