I know if my dad suddenly had to pay any of his 7 employees more money (I think he has 3 or 4 at minimum wage now) he would have to cut at least one person to be able to pay the rest. That is not an insubstantial amount, from the $7 range to the $10 range. Extrapolated over a year is $6200 per employee or so that you might have at minimum wage. For mid-sized and small businesses that will have a real impact. You know, the businesses owned by the "middle-class" business people. The bigger organizations will be able to absorb it ok, but the smaller guys will feel it for real. Talk about warfare on the middle class, this directly impacts middle-class business-owners in a negative way. As One Brow said, I have no idea if the SF area can handle that level of an increase, but I sure hope the small-business owners are able to adjust without needing to let go too many people.
Seems a strange time to do something like that, that at best will have a neutral impact on jobs, at worst will cost jobs, when the biggest issue we have right now is not how much people are being paid, but how many people are out of work.
