Artists are not really the ones we need to worry the most about. Amongst my artist circles, there are some who find ways to make it work in SF (cheap roomshares can still be found in the sunset etc), others who have been able to leverage their skills with tech companies to live comfortable lifestyles, those who have found refuge in the east bay, others still who have found other, cheaper cities they feel more comfortable being in... really there are options for artists.

Those we should feel sorry about are those driving the buses, stocking the shelves at Whole Foods, cleaning the floors at the tech offices, delivering nursing care in hospitals, teaching the children, etc.
