“It may seem ironic that unions are under attack when Washington seems most disconnected from the economic needs of the middle class. But that’s not an irony; it’s a strategy. Critics of unions, such as Gov. Walker, want to cut government and reduce taxes on the wealthy. (Dire budget rhetoric notwithstanding, Walker’s first item of business was to reduce taxes on corporations and the well-off.) And they would much prefer to do it without unions calling them to account.”
