I live in an area of S London routinely slagged off on MN as a shit hole , dangerous etc.
And yet it is full of friendly community minded people. The kids pouring off the buses are polite and respectful even amongst their teen boisterous- ness. My Dc went to highly diverse state primary and secondary schools, with very high levels of kids on FSM, other indications of social stress, the 3 schools we were in were Outstanding (2) and Good (1) and they did really well.
I love the huge cultural opportunities, in England we are never far from our fantastic range of rural, upland or coastal outdoors, or a vibrant city.
The last few years have been depressing. Most people continue to have excellent service from the NHS but the direction of travel and overall stats are not good.
Town centres are often less shiny, we’ve all taken to internet shopping. What do we expect?
This winter has been wet, and the cold persisted a long time. The international news is depressing and disturbing, and surely that is the same from wherever you watch.
There are problems but MN, with a high proportion of people who live on the net who are more fragile about RL than average, from not answering the front door to driving on motorways or joining the literally millions of people who live happy safe lives in S London. So I wouldn’t take MN as a significant basis of decision making.
