No, although slaveocrats were quick to call Northern immigrants working in poor conditions, "wage slaves", and to argue such people were really treated worse than their own benighted slaves.
But to my knowledge nobody was ever confused about who such passages in the Constitution referred to.
Why do you ask?
Because my people , the Irish faced terrible prejudice in America. Whereas blacks were segregated to separate but equal the Irish faced such discrimination, particularly in areas of employment(’’Irish need Not Apply’’.) An ‘’indentured servant’’ didn’t not necessarily mean a black person, did it? But what I’m really curious about is if the South had won the war would the Confederacy have been a separate nation within the US? It’s my understanding that even as it was the Confederacy was not all that bound together. Some of the states wanted even to secede from the original Confederacy, did they not?
