Having lived in NY on an editorial assistant’s salary, I can say it is possible, but not easy. Also, I was alone at the time, and only had to worry about me and my cat. For someone with kids to feed, it would be much harder. (When I worked in NY, I did know colleagues who got by because they had family money and/or spouses with better jobs.)
But the responses from Uber et al seem fairly predictable: “How can we make money/sell our services if our drivers don’t starve?”
