You do not deserve to eat just by existing (unless you are disabled or medically cannot work). Saying this is true implies that you have a right to other people's labor, which you do not.
Land, water, air and light used to produce food are not owned by any particular human either. The monopolization of that land (at the point of a gun most often) is the beginning of the issue. The overuse of that land, often subsidized heavily by taxpayers, in order to generate exorbitant profit for the few is a rot in human society. Those owners are the actual ones who don't work and expect a reward for it
