sam walton wasn’t the problem. when he was alive, he established policies to take care of the employees and buy from American suppliers when it was economically feasible. when walton died, walmart’s commitment to anything other than maximum profit died with him.
i don’t have a problem with successful corporations; Costco and Target are in the same business, and I support both. They both take care of their employees, and offer benefits to all employees.
