Where Breed (and others) are very wrong, is that it is the retail street-front businesses that made San Francisco so nice to live in (If you are into city living at all). Retail means more than tourists, it means residential living for middle and upper class folks. Good activities going on. Enjoyable atmosphere.
I guess that is pretty much history now. The Great San Francisco Earthquake of 1906 did less damage to the city than Democrat policies have done!
In residential areas streetfront retail looks just fine.
West Portal, Cole Valley, etc., they seem healthy enough.
Downtown is the real disaster.
One place that does look bad too (or worse than usual), is the Mission, between 16th an 24th St stations. A heck of a lot of closed storefronts where I didn’t expect it. This was a gentrifying area.
I didn’t get to Stonestown mall. That would be a place to watch.
