I would expect some of that in the reserves. These folks have likely been in a long time, and were caught there when war broke out. I suspect there will be much less of the single mom, or folks looking for college funding, Reservists in the near future, simply because they now understand the seriesness of their being there. I'd expect those who are volunteering to serve at this point would not have the same problems as you saw.
Amazingly, you still run into the "Whaddaya mean we have to go fight? I signed up for the college money." even now. My unit has been deployed 4 times since 9/11 and they still send us single moms, etc.
I still think that you will have reservists who will sign up for the wrong reasons, no matter what. The other problem in the reserves (at least in the Navy Reserves) is people trying to scam out of being deployed.
