Think about what things were like 100 years ago.
Think about what they were like fifty years ago.
And think about now :)
It's natural to feel fraught and anxious about things but it's all just circular. It isn't quite as simplistic as the "seven years of feast, seven years of famine" mentioned in the Old Testament, but just the same there is a period of prosperity and then a recession, then things pick up again ...
If you look at a broader context though, things do improve and get better. After all, one hundred years ago young men were cannon fodder (sorry to sound flippant, I'm not at all about this, it was dreadful) but now the prospects for young people are certainly different to fifty years ago, but not actually "bad."
I think the main differences are house prices - these surged unexpectedly in the early part of this century - but wages will (slowly) come into line with them. We do have a lot of elderly people, 'tis true, but people are recognising this and making provision for a long retirement.
I promise that when we are doddery old women our children will be moaning and groaning about how easy we had it!
