I would say the problem is that there is a big gap between affordable consumer goods and unaffordable things like housing. That makes saving on little things like coffee shops seem pointless, as you are still not going to save nearly enough to make a difference when it comes to buying a house.
I look back at things you could buy 30,40,50 years ago, much of it sucks and doesn’t compare to what you find today. Back then you didn’t need much money because there wasn’t much to buy. I look at the ads and they’re garbage, not engaging at all and doesn’t convince me to want the product. And because people weren’t posting pics of things they purchased to some social media, seeing something cool that I might want to buy usually only happened when going over to a friends house, or seeing a random passerby in the streets. And that meant those people were usually close to your own economic class, so the items weren’t out of your league.
