It kind of sounds like you believe Walmart employees have been sentenced by a judge somewhere to work at Walmart. Do you understand how capitalism works? If no one is willing to work for the offered wage, the employer has no employees and must adjust wages to a level that attracts people to want to work there. However, if an employer is willing to employ low skilled workers that would otherwise be collecting unemployment, then they can pay lower wages and as a result offer lower prices to the consumer. A win-win.
