Well, I doubt anyone would suggest that life was a bed of roses during the war or depression. It could be that there is more prevalence of mental ill health now, or, that we have become better at recognising and diagnosing it now.
Life maybe easier in many ways, however, it may be more challenging in others. It’s just different.
Many countries have been in a cost of living crisis for a number of years. Home ownership may well be nothing more than a distant dream for many young people. With rampant inflation, and wage stagnation, wages have seen a real terms cut. Most people feel the pinch. In the UK, more and more people (many of whom work) are using food banks.
Arguably, Gen Z and Millenials have had it harder than their parents, financially speaking.
You worked in administration, which is only one profession. I would imagine that health and social care workers (in the NHS anyway) would tell a different story given underinvestment for decades. There are entire teams that are struggling as they cannot keep staff (see point above re wage stagnation, resulting in unpaid overtime, increased workloads etc.
I agree that people can, and should, limit time on social media. It is detrimental. But, easier said than done. In my own family, the worst users of social media are actually my parents (baby boomers). Some suggest that technology and devices are addictive, and the younger people are when use starts, the more detrimental the impact. Which means that a while generation was raised with it before the impact was known.
