Update, 2/5/07: Mike at EIA (see blogroll at left) has this comment about teacher pay and unionism on the February 5th Intercepts:
Union spokesmen knocked each other over to claim that teachers are woefully underpaid – you can check out this sampling from Michigan, Iowa and Ohio. I've never been able to square this with the accompanying claims of the benefits of unionism. Forty years of collective bargaining and political power and teacher salaries still stink? Time for a new direction, if you ask me.
Hard to argue with that logic.
