As far as unions go people, the plural of anecdote is not data.

The IMF, the OECD and the World Bank have all issued recent reports that say global economies need more worker representation to get them a bigger slice of profits as the current distribution of wealth is so unbalanced it's badly damaging the global economy.

American unions may have corruption problems and do things that seem in favour of even bad workers against the businesses they work for but every single major institution in America has the same problems.

Go to Germany and every company over 20 employees must allow a union and furthermore has to have a union representative sitting in with the managers and board of directors and making decisions with them. Seeing as hoe Germany currently has an unemployment rate far smaller than America's, a massive trade surplus and fantastic industrial relations with well-paid well-trained staff then clearly there's a place for unions. The heads of the world's major global financial institutions all think so too.
