When I look at the list of demands I'm pretty quick to dismiss it. Then I remember how I dismissed the 1999 WTO protests in Seattle too, and how many of the fears those protesters had were realized over the next two decades. I might be too hopeful, but I really think the city leadership should talk to them and hear them out, instead of just trying to push them over.
Note that rent control, even if the city doesn't have the power to establish it for private rentals, can effectively be achieved by the same means.
