I hate to say this, but there is no job in Walmart, that would deserve a $25,000.00(except mgt) yearly pay wage. One doesn't need a college education to stock shelves. Yes we offer health insurance, the premiums are high, imo, however....
If they did raise the living minimum wage, are people who have been there a long time, and have busted their asses, are their wages going to reflect that raise?? probably not....

For most people, it is a stepping stone to something else, or supplemental income, as (Mrs Smith?) said...
