In any case, however, Mr. Ryan was more right than he knew. For what’s happening in Wisconsin isn’t about the state budget, despite Mr. Walker’s pretense that he’s just trying to be fiscally responsible. It is, instead, about power. What Mr. Walker and his backers are trying to do is to make Wisconsin — and eventually, America — less of a functioning democracy and more of a third-world-style oligarchy. And that’s why anyone who believes that we need some counterweight to the political power of big money should be on the demonstrators’ side…

You don’t have to love unions, you don’t have to believe that their policy positions are always right, to recognize that they’re among the few influential players in our political system representing the interests of middle- and working-class Americans, as opposed to the wealthy. Indeed, if America has become more oligarchic and less democratic over the last 30 years — which it has — that’s to an important extent due to the decline of private-sector unions.

And now Mr. Walker and his backers are trying to get rid of public-sector unions, too.
