I don't think anyone would suggest that slavery was an exclusively american concept, but there are ways that slavery impacted america and is still impacting america that i don't think is true of other first world countries (e.g. how financially dependent early america was on it, how late in history relative to other countries it was abolished, how it was one of the causes of the civil war, which in turn significantly shaped america, etc)
