here’s my misc thoughts lol i’m no expert but this is from my POV as someone who’s lived here full time a bit and grew up visiting all the time. firstly, you’re def right that it is expensive — nearly impossible to relocate to if you don’t have a job secured and aren’t rich. even moreso if you have never visited or have only done one super tourist-y visit--it’s not just Times Square and Statue of Liberty (love her tho) rainbows and butterflies vibes lol.
like i seriously do not recommend moving here if you haven’t been to other boroughs, and neighborhoods outside of Midtown, SoHo, FiDi, UES etc. i’ve never been to england so can’t speak to it bit you might find it helpful to look online for comparisons to cities you’ve spent more time in - london and other cities in europe perhaps. consider if NYC would be that much more exciting or “better” for you?
also there’s a huge issue of influencers and people who wanna live here impulsively for fun that has driven up rent and driven out lifetime residents, esp working class folks and people of color. (lots of writing out there on the difference between moving to any city vs gentrifying one, and what one can do to not be complicit in the latter). and, my family is from here and i have always loved the city; i did get a job here after graduation but i really wouldn’t have moved here if i hadn’t.
so definitely come here intentionally, and arrive with a willingness to engage with your community! sometimes new residents who aren’t as acquainted with the “real” new york and can’t afford apts in the more gentrified or historically wealthy areas (most of manhattan, some parts of brooklyn) have a misconception of the city, so they end up feeling awkward or “unsafe” where they live, and thus don’t give back to their neighborhood. it’s veryyy weird that some people move here only to go to work, eat out and party on the weekends. (not saying this is you ofc! but just a general note).
the irony is that NYers get a bad rep for the mind your own business culture and realness--and yeah NYers aren’t “nice”, but people are kind. folks care about and actively help out their neighbors. i saw this in my own fam growing up! and as sinatra himself once said: “if i can make it here, i’ll make it anywhere.” it is a tough place to “make it” for people without roots. but i’d never deny that new york, for many of us, lives up to its reputation as the so-called greatest city in the world ;)
