OP with a few caveats I think YABU, for all the reasons already stated above. I would hate to have been a woman living in pretty much any other period of history other than this one - or, for that matter, a man who was outside the perhaps 5 or 10% of people who made up the elite/aristocracy. (I'm no genealogy expert, but I'm pretty sure my family come from peasant stock, and my DGM was one of 8 siblings to have grown up in a Hoxton slum, so belonging to any past elites seems distinctly unlikely!)
While I agree that many people in the UK are struggling at the moment, you don't need to travel that far to find places where things are much worse - I spent time in Italy this summer, and was shocked at the very obvious poverty and social discord I found there, especially in the South. There was a real feeling of malaise, and a sense of hopelessness among many Italians I spoke to - especially the younger ones, who had no prospect of any real future in Italy. The economy there is almost completely stagnant, and the infrastructure is crumbling to an extent that makes ours look positively new and sparkly. Many of them saw the UK as a utopia in comparison.
However (and here's my big caveat) - this isn't a message that many people want to hear, but I do think that the boom times of the past few decades are over, and that we (throughout the West, not just in the UK) are going to have to adjust our expectations accordingly. If we want to sustain the level of public services we've become accustomed to (notably the NHS and social care), then we're going to have to pay more tax. Most of us will have to rein back our spending on things that in the past would have been considered luxuries - clothes, holidays, meals out etc., and these things will revert to being luxuries again. Food prices will have to rise due to climate change and global population increases, and we'll have to be more thoughtful about the food we buy and where it comes from. Basically, we're going to have to pare things down and simplify our lives.
The one aspect of modern life I do regret is the way that multinational corporations, rather than governments, now seem to pull most of the strings. In that respect, I do think that things have definitely got worse.
