Are you blaming the exorbitant cost of prestigious private education in the US, the crippling student debt system, and the unequal access to social advancement opportunity, on employers being unable to test prospective employees' IQ?

I'm not sure that the whole story (but then again I've never been within a couple thousand miles of the US, so what do I know), but tuitions in the US are one order of magnitude more expensive than in continental Europe and this one is the only thing I've heard that even begins to explain that.
