While I think tenure should be eliminated, the reason why the lack of tenure-track jobs is becoming a problem is that people trying to find academic openings have a very hard time doing so, much less actually snagging one. If they find one, it is likely just a temporary gig with pay that won't put food on the table.
Only tenure-track positions provide any kind of job security or decent pay.
The problem with tenure is that it goes too far and effectively makes it impossible to fire somebody.
I don't want to discourage any conservative from becoming a professor. The work is brutally hard and the pay (at a small college) is less than in the public schools. But you really are boss of your own time and if you guard what you say you can get off as nicely non-political.
In the secondary schools, you will find yourself hand-cuffed much of the time.
If you are successful as a professor, you really do make a difference and are appropriately rewarded.
Having said that, the cost of faculty politics can be terrific.
I like my job and would not like secondary schools. I really do have control of my classroom, my research and my contacts with students and other people.
So, there are ups and downs to both sides.
Good luck to both of you and if I can give you a hand or some advice, freepmail me.
