Very few escorts can survive without a day job. In big cities like NYC or LA, there are just too many escorts and not enough clients willing to pay. Many good ones ended up quitting because it is hard to survive being escort alone. There are a lot of costs to live in big city: rent, gym membership, transportation, food, phone and internet bill, advertising cost etc all going up to the roof and with cancellations, no show and faked clients, many escorts ended up in poverty. It is a cut throat, dangerous and emotional wreaking kind of job if one just relying on being an escort as a sole source of living.
