Both places share the values of giving back without expectation of an immediate return and betting on disruptions to big markets.

FORBES: Why FiveStars Moved From Silicon Valley to San Francisco

If the Fed had a standing, credible commitment to keeping nominal incomes growing at 5.5 percent in 2008-2010, speculators would have effectively helped the Fed achieve its goal by buying up assets before they fell too far, in expectation that future Fed intervention would cause those asset values to rise again.
