To play devil's advocate for a moment, if someone is majoring in Ancient Egyptian, Greek or Roman history; I'm not completely sure U.S. history would really be relevant to the degree. Of course personally I think anyone majoring in History at a US college should at least have some classes in U.S. History even if their specific major is foreign or ancient history.
Now all that said. When I took a U.S. History course at CU in Boulder CO back in the early 90's required reading was Cornell West; so I'm not sure U.S. History classes are actually teaching factual U.S. History to begin with.
