I think that part of the problem is that what people were once content with - affordable home, family life, a bit of fun on the weekends and freedom and time to pursue talents and passions for their own sakes have all been turned into consumer pursuits.
If you don't want more - more money, more status symbols, more of anything really, it's seen as a bit of a failing. The worst thing you can do is be content with your lot in life so it seems things are being engineered so that's the impossibility as paying for the basics consumes every moment - not for individual benefit, but to keep feeding the machine, else society will judge you.
Yes, and the horrors or celebrity culture, reinforced by social media, have done a lot of damage.
A careers teacher I knew often reported that the non-academic boys he worked with had wildly unrealistic expectations for their employment. He would invite experienced professional tradesmen (plumbers, builders, electricians etc) in to give talks and the boys would sneer and say 'I'm not working for that money - I'm going to be a footballer/model/'celebrity. The unrealistic expectations set up by the culture of glamour and celebrity is really pernicious. These boys thought that learning a trade was far beneath them.
I'm afraid I used to be a bit cruel when I encountered this attitude. A 15-year old boy I taught who wouldn't even lift his pen, when challenged about his future prospects, said "I don't care, Miss, I'm going to be a footballer when I leave school". I know I was being a bitch but I couldn't resist asking innocently 'Oh, so which club have you been spotted for?" It was a complete revelation to him that if you have any chance of being a pro footballer, you'll have been talent-spotted at lower secondary age and be involved in training already.
