We have a piece up on the homepage by Mario Loyola comparing Houston and Detroit as political and economic models. It ran in our last issue. After we published it, it came to our attention that Mario’s think tank, the Texas Public Policy Foundation, has a relationship with Gov. Rick Perry (as reported here, it gets royalties from Fed Up). Mario didn’t mention it to us, because he thought it was already public knowledge and his piece isn’t directly about Perry, let alone Fed Up. If we had known, we would have acknowledged it in the interest of fullest disclosure. But the piece stands on its own, and I know Mario — a friend of mine for years — sincerely believes everything he writes. Please give the piece a look — it’s excellent.
