Being one of those "mommy and daddy's bank" imports in NYC, I can say making friends is hard not because snobby people but people literally don't have "A MINUTE". I think what needs to be understood is no matter how much you are supported financially, it doesn't matter, there is always better, richer, more talented in NYC. There's always competition, no matter what level you are at. So even if you're financially secure, just thinking about the amount of competition and the effort needed "to make it" is stressful. I"m not even including everyday stressors like all the noise, dirt, rude people of the city you have to bear.

Of course there are snobby people, in fact a lot of them. But I think the issue of friends in NYC goes more like

At first you meet some people but you have so much to do, you meet them at times but not a lifetime long. Also any service you can think of can be bought in NYC, So people don't get to have history together and don't usually make sacrifices for each other, help each other's ass (which usually bonds people and builds long term friendships)

You meet lots of people, LOTS. (including top famous people) And like every other thing, there are always better people too. So at the end of the day when your "possible-future-friends-to-be" ask you to hang out, you can sometimes end up thinking "hmm I should better hang out with those arrogant group of designers this time, they might include my project in their next issue"

Or when you finally get home and get asked to hang out "gosh i slept 3 hours yesterday so I'ma netflix"
