Good Points. I would add that the demand for a 4 year degree is not strong by itself, but that it is often required by many employers and used as a differentiator, even though a degree may be immaterial to the position or industry. So there is a third party source propping up demand. Until that stops, there will be no move towards the convenience end of the axis.
