[讨论]concentrations strength or location?

Which is more important in finding a job in USA, concertrations strength or location?

Some schools with good reputation and high rank in particular fields may locate in a small town, but they will do much better job in advanced education and the aluminus is truly a critical factor in future career success.

But it is also ture that big cities will provide much more job opportunies.

个人认为没有绝对的答案，也没有办法印证这种答案。

具体个案，具体分析。
