Thats like asking, "Can there be enough people doing things with a population of 6 billion?" Jobs aren't a finite resource, they just consist of people doing enough things to convince people to let them get to enough of the food and shelter. The threshold most people place on the difference between having a job and not is usually around "I have enough to eat, and a place to sleep". Or was your question, will there be enough food that's possible to grow on earth to feed everyone? Some ted talks I've listened to say no.
