I agree with many of your points except the quality of food. I suppose it depends what your starting point is, but I'm in my mid 40s & in my lifetime the overall quality & in particular the availability of decent quality & interesting food has improved hugely in this country. In the 70s, 80s and even 90s a lot of British food lived up to the stereotypes, much of it was pretty basic and uninspired, and ultraprocessed food had really taken off but we didn't realise how bad it was at that point.

Personally I was lucky I grew up in a middle class family with a mum who was good at cooking, so I mostly ate pretty decent food at home compared to some of my peers, although even then the range of ingredients available to us was pretty limited compared to today, especially in a medium sized town like the one we lived in.

There are loads of foods we take for granted now that are sold in every supermarket which you would have only been able to get in specialist shops in big cities if you were lucky. And the range of some fairly basic types of food, e.g. cheese or bread, was pathetic compared to what we can get today. Camembert was the most "fancy" cheese you could get, and even that was considered a bit much by most people! And bread was basically just white, brown, granary and baguettes. Sourdough or all of the interesting varieties of flavoured breads you can get in most supermarkets were largely unheard of.

There has been an explosion of "artisan" producers which has had a knock-on effect on what's available even in supermarkets, and has raised standards and expectations overall.

International food was largely a pale imitation of the "real thing" - I thought I didn't like curry until I went to uni in Manchester and tried a "proper" curry, because I'd been brought up on weird 70s British curries, usually made with low quality powdered spices that had lost half of their flavour, and served with things like sliced bananas and raisins for some reason!

Restaurants have massively improved too, as well as the range of restaurants available. There are cuisines available that people hadn't even heard of when I was growing up, and the overall standard and range of food in restaurants has significantly improved, as well as the culture of eating out.

And if you just wanted to grab a quick bite to eat for lunch the choices available were often awful, sandwiches were usually a limited range of pretty boring sandwiches (e.g. ham, cheese & pickle, egg mayonnaise) often served on sad looking bread, and none of the things you might grab for lunch these days even existed in most places e.g. sushi, wraps. American style fast food had massively taken off by that time, but the quality of even that was poorer than today. Greasy spoon type places were often your best bet for a decent lunch. I have fond memories of our childminder taking us out for egg and chips!

"Salad" was just lettuce, tomato, cucumber and not much else. I'd never even heard of alternative salad leaves like rocket until I was a teenager!

The one thing I would agree has declined is the quality of a few classic British foods that used to be reliable in my childhood but have gone downhill in recent years, Cadburys chocolate being the most obvious one. Cadburys was considered to be "good quality" chocolate when I was younger, but since being taken over by Americans they've lowered their standards and it's just not the same. But thankfully alongside that there has been a huge explosion in the range of other quality chocolates available, back in the day the only options significantly better than Cadburys were things like Belgian style truffles which were considered the height of sophistication in the world of chocolates!
