No they aren't. I mean, some are, a small few -- but the rest are vastly benefiting from living in a City with a capital C. I could list a dozen ways. And Austin has handled the transition smoothly. ?!?When an area becomes rich it typically doesn't happen by enriching the people already there, but by pushing them out and replacing them. Of course longtime inhabitants want to "go back to its divey roots", they're directly threatened by the move away from those roots, and a return would provide relief.
Keep in mind you're still an outsider and gentrifier in the context of Austin. You're a well-educated white man originating from a rich neighborhood of Dallas. You're exactly the kind of person they're afraid of, and not without reason. Things that are good for you are not necessarily good for Austin as it was or the people who live(d) there.
