Paul Krugman's Sunday column is an essential read:

Specifically, language virtually identical to Florida's law is featured in a template supplied to legislators in other states by the American Legislative Exchange Council, a corporate-backed organization that has managed to keep a low profile even as it exerts vast influence...

What is ALEC? Despite claims that it's nonpartisan, it's very much a movement-conservative organization, funded by the usual suspects: the Kochs, Exxon Mobil, and so on. Unlike other such groups, however, it doesn't just influence laws, it literally writes them, supplying fully drafted bills to state legislators. In Virginia, for example, more than 50 ALEC-written bills have been introduced, many almost word for word. And these bills often become law.

Many ALEC-drafted bills pursue standard conservative goals: union-busting, undermining environmental protection, tax breaks for corporations and the wealthy. ALEC seems, however, to have a special interest in privatization -- that is, on turning the provision of public services, from schools to prisons, over to for-profit corporations. And some of the most prominent beneficiaries of privatization, such as the online education company K12 Inc. and the prison operator Corrections Corporation of America, are, not surprisingly, very much involved with the organization.

What this tells us, in turn, is that ALEC's claim to stand for limited government and free markets is deeply misleading. To a large extent the organization seeks not limited government but privatized government, in which corporations get their profits from taxpayer dollars, dollars steered their way by friendly politicians.
