There are multiple meet ups every weekday night in NYC. You can connect and network with people quickly and efficiently. And for free. The economy is booming. And like everywhere else there's always a need for good smart people.
Do not listen to the OP. If you really want to move to NYC then do it. The worst case is that you don't manage to find something by the time your tourist visa is running out and you have to leave. But you would have hopefully made some contacts/connections for the future and had a life experience in the process.
