You can tout Wall Street all you want but not many out side of your city see them as a good thing, most of the country sees them as a parasite with too much political power and way too little oversight. SEC, Secret Service, FBI, and DOJ be damned none of them have gone after them with any rigor.
You also don't have a good grasp on your own cities history. There as a time when manufacturing and textiles was its biggest industries. Yet you managed to drive them all out. If we decide to stop sending you food and gas you city comes to a stand still. Then you can have hungry entrepreneurs on every street corner...
As far as the industrial history, yeah, service economy, information age, yadda yadda.
And I agree on Wall St, I pretty much despise them. But if you're going to preach unfettered capitalism via low taxes you should be worshipping it.
When talking about competition over housing, you have a somewhat fixed supply but high competition on the demand side. In that case, prices go up.
While Austin may be an "exciting" center of research and technology, it's hardly a "job creation" engine -- at least not directly.
Texas's top industry: Defense (100% government spending).
Texas's 2nd industry: Oil (government subsidized, and having oil is surprisingly not a function of income tax rates).
Texas's most exciting economic area: Liberal Austin.
I'm not going to rip on Texas but it's gotta be awfully hard for you to feel free-market-superior to the city that has Wall St in it and an entrepreneur on every single street corner.
