expand upon the principle; nobody should be required to justify their right to a dignified existence by engaging in work (the system by which we sell our labor to the capital-owning class, but have no control regarding the means of production or resource allocation, and no guaranteed equitable access to quality food, shelter, medical care, or education..)
If you do it for a full day then yes it is. Whatever your opinion of a job is, if you want it done by someone then that person deserves a living wage.
(btw, I hope I didn't misunderstand your point, not entirely sure)
Walking dogs is not in demand enough for someone to have a living wage, what's that, like 13 USD the hour? That's poverty salary in lots of places. Certainly not enough to make a living if we go by the ethos of the "eat the rich" crowd
I don't know about the "deserving" part as that is subjective.
