Was born in a different country, but moved to London in early childhood and - bar a couple of years living elsewhere/travelling - have been here ever since, and raised my kids here.
If I think of the London of my twenties, a lot is 'better'. Run down areas like Kings Cross or the South Bank are vastly improved. There seem to be a much wider range of places to eat and drink, and the quality is better. In terms of the arts and cultural sectors, I think things have improved a lot too. Our museums and galleries - often free - are one of the best things about this city. I really notice the difference when I visit other countries. It's such a vibrant and exciting place to be.
However, it feels like a much harder city to live in now. It's more polarised. The problems with deprivation, homelessness, poverty levels etc - it's all worse. Aware there are failing state schools across the UK but it's a very rare London comprehensive that doesn't have significant problems right now. That simply wasn't the case when I was growing up.
It's now much harder to be a young person embarking on a career, particularly badly-paid, creative careers. It used to be quite easy to rent cheaply in central(ish) areas like Camden or Notting Hill - that's totally gone now. Getting on the property ladder feels like an impossible dream, and I worry about how my kids will stay here themselves.
On a more minor note, it also feels too busy at times. Almost every public event seems uncomfortably packed and overcrowded, and things get booked out so quickly, it feels less possible to have a spontaneous day out, which is a shame. The traffic is so much worse. Aware we should minimise use of cars, but it used to be quite easy to drive places if you needed to, or get a cab home from a late night out - now that is difficult and/or prohibitively expensive.
So...I would say there's lots of issues. But I still wouldn't want to live anywhere else in the UK.
