Did the demographic change/continue to change because it was forced or because it was the natural progression? Would the same apply for a service in the military?
Job's aren't easy to find for many right now, and retention is up, not to mention the fact that many services will shrink their work force. I think the "incentives" notion is of keeping people in doesn't apply as much in 2010. The incentive these days is to "have a job", which is why promotion boards have become a blood bath.
When Adm Mullen became CNO he commissioned a study to evaluate the vision of the Navy for the entire 21st century. One of the areas studied was the demographics of the recruiting base for the future. The nation is getting older and it is getting darker. The base from which the Navy has traditionally obtained the majority of its recruits is shrinkiing. Also, technical expertise requirements will increase with our future Navy. Remember that traditionally the Navy has been the whitest of the services. The conclusion was that the Navy could not survive the 21st century without expanding its recruiting base. Hence the diversity focus.
Yes, we are in the middle of a recession. No, the recession will not last forever. So no, one year does not a trend make.
If we don't be proactive on this, by the time the need shows up in the recruiting percentages, it will be too late. Our combat readiness will already have suffered irrevocable harm.
