Chicago's new retail living wage law is another kick in the pants for Walmart & other big-box stores. It's especially effective because it challenges those stores to live up to their assertions -- i.e. big-box development supports local economies and creates quality job opportunities. The fact that Walmart, Target et al see this legislation as a significant barrier to store development demonstrates clearly that poverty wages & benefits are part of their business plan. Their low prices (and enormous profits) depend on extremely low labor standards both here and overseas, and these companies remain completely unwilling to compromise on either side.

When John Simley, Walmart's spokesperson, argues that this legislation "means that Chicago is closed to business,” that's what he's saying. A more honest statement would be: "Chicago's closed to our exploitative, damaging business model."

The Brennan Center has detailed information on the ordinance, including the actual language.
