An important note about the Texas Miracle
We're seeing one drawback to it right now: houses in Austin built in fire zones because they ran out of room.
But the key thing to remember is what that is a side effect of: even if the Miracle™ had really done all Perry et al. say it has (which is debatable), it's not replicatable for the whole country. The Miracle depended on siphoning off business and workforce from other states.
The whole country can't siphon them off, because there's no place to siphon them from.
