Creamy I think it would be a exercise in futility.
A lot of people in this country could give a rats ass about their neighbors or fellow worker. If it means they can save a nickel on a bottle of Ketchup, then so be it pay the worker less or do away with their health insurance.
The funny part is these people don't understand Walmart is just being subsidized by the tax payers. That's right, when that worker is so poor they cant afford to feed themselves or their families, who do you suppose does? FOOD STAMPS. When they don't have medical insurance and are on Medicare who do you suppose pays for that? You taxes dollars once again.
So you support a company that is raking in billions while they have pushed the burden of paying for their workers on the US tax payer. How bizarre is that...
