Pay employees a low wage, keep costs low, export dollars out of the local economy to the home office where the real compensation is paid. That's the net economic effect.
When they add produce to their stores, the local grocery stores lose business and in small towns, our local grocers tell me it will put least one local grocery out of business. So the community loses another business owner and the money he would have made that would otherwise stayed in the community also gets exported to the home office.
If they sell tires, then it hits the local tire stores.
Do you want local business owners or a bunch of wage earners?
