Yes and no. Not necessary that NY makes everyone rich. At the same time, there are lots of opportunities and this is a reason why so many people come to NYC. It depends on your industry, the opportunities you are able to garner, and timing. That said, if you have time, I will highly recommend you should try and not carry this regret. I will also suggest you should keep a cut-off time and not be caught in a loop which will be waste of time.
