Chickens and Eggs of Ecclesiastical Deterioration: Which Comes First?

One of the panel members at the ACCC Convention discussion forum (I think it was Dr. Colas) said in reference to the institutional influence on contemporary evangelicalism, "As go the schools, so goes the movement."

Is this true? Do educational institutions really drive the bus, or do churches? Did the denominations of the 19th and 20th century fall into disrepair because the schools hired modernist faculty, or because churches were in such disrepair that they failed to lead and exercise oversight? Is the SBC conservative resurgence succeeding because the seminaries changed, or because churches rose up and began to fight for the gospel and purge the seminaries?

This raises an interesting question. Fundamentalist leaders decry the the trend of younger men who are leaving "the movement." Is this because fundamentalist seminaries are unhealthy, or because fundamentalist churches are? I'm only one dude, but I'm pretty sure it's the latter.
