You know, folks should rethink that "punch any DM who wants to get paid" thing. Because there's nothing wrong with getting paid for a job you find enjoyable.
If it were a job, the DM should get paid in accordance with how much entertainment he or she provides.
If you treat your DM like a movie - an individual person in a metropolitan area will pay something like $3.25 and $4.50 per hour of actual entertainment time. Call it six players, you're talking in the neighborhood of $20 to $25 per hour. Of course, you probably prep for at least as much time as you run, so you're talking an effective $10/hour or so.
If you treat your DM like a novel - an individual gets many more hours our of their $8. Each player will then net you less than $1 per hour.
And that, of course, is if you're really professional grade.
If you're really good, maybe you're more like a low-end theatre ticket - between $20 and $30 per hour per player. But you'd have to be four-part harmony with feeling and special effects to rank that high.
