I think it's a necessary hope to instill to the younger generation than let them realized the full weight of being an adult in today's current society.
I don't, firstly because kids aren't stupid and most of them already realise this, which is why so many of them are being irresponsible selfish brats that older generations look down on for having atrocious work ethic and being irresponsible selfish brats, and secondly because this would be how this sheer bloody minded idiocy keeps perpetuating.
I'm a one of the top performers in class and in a profession that's ranked 5th or 6th as the top paying profession, my lifestyle is about being thrifty
Similar position (J not me) and people are constantly amazed we're not rich with an easy life (it's not difficult by any stretch, of the imagination, just a bit tight).
We still taught the kids to save but it became more about stockpiling than anything else because it looks like you need to keep doing term deposits or something to make that go anywhere.
