I don't see this as a good thing because the companies will move south and bring their "yankee politics" with them,as well as many of their yankee employees,who will IMMEDIATELY start demanding their new state pass laws like their old states had.
I have lived in southern resort cities and seen this for myself. The first few months they all want to talk about how great where they live now is compared to where they used to live,but by the years end they are demanding additional gun laws,additional zoning restrictions,etc,etc,etc.
I say we should keep the bastards out and let them stew in the piss pot they created up north.
I guess it would be ok to hire a few for seasonal work as laborers in the summer,but only if they are deported in September.
