Missouri House members have voted to cap the state's minimum wage at the federal rate. The legislation would essentially overturn a 2006 voter-approved law that lets Missouri's minimum wage rise above the federal level based on annual inflation. Proponents contend capping the minimum wage would help small business. They also say it could be difficult for Missouri businesses to compete if the state's minimum wage is higher than those of neighboring states. Critics defend Missouri's existing law and say legislators should not overrule a measure approved by the voters.
