>That's an 89% increase over a decade, and a 32% jump in just two years. San Francisco has the highest indexed concert ticket prices in the nation, roughly 29% above the norm, according to analysis from Tickethold.

Of course prices are increasing everywhere across the USA. I am just pointing out that San Francisco has always been significantly more expensive than everywhere else even before the last handful of years. And the reason for this is very clear: SF people have been paid more on average. Probably because the demand for the small area (so nice climate wise, job availability wise, etc) exceeds availability for those things and drives up other prices. And then the ratcheting like I said.
