There is a massive psychological difference between being young, having nothing, and working hard with something to look forward to; and being young, having less than nothing, and working hard with nothing to look forward to.
And I don't agree about hardship, in many ways. When I had measles in about 1978 (? thereabouts) the GP paid a home visit and was expected to. My brother was a newborn in the 70s and the MW came every day, sat and chatted. My mum had 3 or 4 days in hospital after a perfectly normal delivery and was well looked after and rested when she came home - she was expected to stay in so she could be brought meals and stay in bed resting.
Most of my friends at school had dads in blue collar jobs, mums who WOH very part time if at all, and owned 3 bed houses, and the whole family had dinner together at 6pm and had all weekend for hobbies and pastimes. We are just so strung out now. Lives like that are beyond our grasp. A smart phone just does not make up for it. Our labour does not buy us as much as it used to. My partner and I WOH between us a minimum of a 110 hour week (in good jobs) for the same standard of living I saw families with one blue collar worker having in the 70s on a 45 hour week. And we will not retire at 60 / 65. And I still suffer from pregnancy complications now my youngest is over 2, because I can't get medical attention (have tried, have been brushed off, can't find the time and energy to fight, although I know I should, but I am ALWAYS working)
And it is far far worse for those 20 years younger than me. I started work nearly 20 years ago as the most junior in a team of people. Since then I have been gradually promoted to the level of the person who in 1994 was about 5 people above me. (Different companies, equivalent teams) In that time, almost NO duties have been taken away from me. I do what I did in 1994, along with everything else at every intermediate rung. And I am on my own. When I feel like moaning about this, I remind myself that at least I have a job - the 22 year old equivalent to me back then, has nowhere to start, because one man bands like my "dept" can't hire. I would rather be me now, working, than a 22 year old in 2013.
I think we have an anachronistic cultural tendency to think the young have it easy, and the older are seasoned strivers, because it used to be true. It used to be true that anyone who was 60 or 70 had probably fought in a war, borne children at a time when many people died of it, worked down mines, survived when some of their siblings had died of childhood diseases, worked hard to get an education in their spare time when the state chucked you out of school at 14, etc etc etc. Baby boomers did none of this. Their parents fought the second world war, they were sent to university for free, they experienced incredible effortless growth of wealth if they bought property, and now they are retiring early.
As a society we need to recognise the difficulties that the young face.
