Well, I think England is certainly different, even from the 80s and 90s. But that doesn't make it 'not England' , it makes it 'modern England'. Countries change through history all the time, surely; we can't just expect things to stay the same.
In my opinion, it's neither a good nor a bad thing because some things are better, some are worse and some are subjective or dependent on who you are.
Better example -
Better equality for women in the workplace and, for the majority, at home.
Worse example -
Health and Safety insanity and lack of freedom for our children.
Subjective example -
I live in a home counties village and work in a fairly 'posh' prep school. In the 10ish years I've been there the school has gone from 3-5% BME to 15-20%BME (though a smattering of those are actually international students, not BME individuals). It's also gone from around 5% SEND to, again, around 15-20% SEND. Personally, I think this is a positive thing. But there have a (very) small number of people who say that this is not the school culture they chose and have voted with their feet.
