I think you're missing a crucial point. Back in the day (I've just recently realised I'm a Boomer given the apparent reclassification of such) there were not so many service outlets, nor was there the diversity of such outlets. We'd hang about in local BlockBusters hoping someone would return a copy of the most recent 'must see' while we browsed! lol
Anyway, I digress. My local high street is now almost nothing but service outlets e.g. food takeaways, sunbed salons, beauty salons, hairdressers, cafes etc. etc.
The point I'm attempting to make is these outlets are supported by (allegedly) 'disposable income'. They would not exist without demand, yes?
It's certainly not the Boomers, in my circle anyway, who are demanding more of this type of outlet, so the nature of the demand has changed along with the volume of outlets for (allegedly) 'disposable income'. Btw, us Boomers (generally) would much prefer to see specialist shops - butcher, fruiterer, independent bakery etc. than yet another fucking nail salon.
No doubt, if anyone actually reads this, I'll get pillioried but I don't genuinely believe the 'disposable income' that has created/supported these outlets actually exists for the vast majority of people.
When I was still a member of the workforce, a few years ago, I was astounded at what younger colleagues were putting on credit cards (manicures, fast-food takeaways for their kids, hen weeks/weekends etc.) with no means of paying for them beyond making minimum monthly payments - not out of necessity, rather than to avoid losing face amongst their (to me) equally deluded friends. They were happy to admit to us Boomers they were struggling/worried but not, apparently, to their 'friends'.
Treadmill consumerism, imo, and a pretty poor friend group where, apparently, none of them could say "I can't afford it so, sorry, I can't fuck off to a villa in Benidorm for an entire week to eat 'chocolate willies' and drink cheap sangria ..."
There you have it: a Boomer rant.
