Texas's growth has come from the rich growing richer. Like any bubble, just below the surface Texas consistently remains a terrible state if you aren't rich and white. 9th largest income inequality gap in the nation, chronic corruption (up to and including Perry himself), and a heap of skeletons in the closet.
It's amusing to see liberals spout that class warfare statement given Obama's own record on 'income inequality' as you put it.
Which is atrocious. Right.
Unfortunately, for leftists, American politics is increasingly a game of less-bad options.
It doesn't have to be though. Progressives really need to create their own Tea Party movement to take control of the ideology of the Democratic Party.
Some of us have been trying (and it's been working in some states, mainly in New England), but it's incredibly hard to do on a national level because the right has controlled the dialogue for a few decades now (not implying anything sinister about the right (pun intended), but that's just the way its' been).
