I kind of agree with your point, but you really think an average licensed plumber in SF makes $200/day???

Well, I did a cursory search for data, and it seems to indicate that this is the case.

So yes... I think the average plumber in SF is making about $70k/yr. (so ~$300 per day worked, or $200 per day).
