You can't buy cool.

In San Francisco we  have a neighborhood called the Mission that was once an  Irish neighborhood, then Hispanic neighborhood. The Mission District had a cool gritty edge to it. Financially well off 20 somethings could feel  this coolness, and decided to move into the neighborhood en masse. Now the neighborhood is quickly filling up with privileged college educated young people, and has become an unappealing brew of snobbery and entitlement.  The irony is in the process of  trying to buy the cool vibe of the neighborhood they have killed what made the neighborhood appealing.
