One thing I always seem to be discussing with friends is that kids never expect to suffer a dip in material circumstances. When they are living at home they enjoy a very high standard of living because they are benefitting from 30 years of their parents labour, and they can't envisage their standard of living dropping
When I left home for Uni I expected to be substantially poorer, and I was
What shocked me was when I started work, I was even worse off, and the reality was that it wasn't until I was well into my 30's that the car insurance bill (or any other chunky cost) dropping on the mat wasn't a financial disaster
The kids I know in late teens/early 20's all seem to expect to eat out at least twice a week, in addition to clubbing nights and weekends away - blimey, I can't afford that and I have a very decent job!
Looping it back to the OP, they can't afford the lifestyle they want if they go out to work, but if they stay at home they have most everything they want, esp if they have soft parents (+ wifi)
These guys are living in the present and not looking forward to any future, because it's all too difficult and they cba, and in a way, who can blame them?
