Well, in terms of call centers and whatnot, there are several big ones in Appleton. But I guess there are big ones in GB, as well. Have no hard data, just used to live in GB (and work in Appleton, twice) and know the area fairly well.
Everyone else has to pay minimum wage which means a US location can't legally be competitive on cost alone with India, the Philippines, or where have you. Prisons can Shawshank their inmates and undercut foreign workers though. You might, and I stress might, be able to do something similar on an Indian reservation but good luck getting workers since any other job has to pay them minimum wage.
