In my area there are no white employees in any businesses that serve the public where blacks frequent the establishments. The open borders are in part to alleviate this problem; when a segment of the population does nothing for themselves, we have to import foreigners to do it for them.
It is important to have immigrants man these hazardous positions. Serving food to the Feral Ghettopotamus is a very dangerous task. By employing immigrants, we have an endless supply of replacements as they are killed over time.
