I served from 1966 through 1990, so I have extensive experience with both the draft Army and the volunteer Army. During my year in Vietnam we had a mix of draftees and volunteers, with the larger proportion being draftees. Of course the volunteer Army was of a higher quality, and certainly more motivated to do a good job. But a draft military still worked, and when thinking about WW2, worked pretty damn well. The two problems with an all volunteer force is, first, that we cannot maintain a large enough force to meet multiple challenges worldwide, and strategically it might be an irreversible mistake to forego involvement because of the lack of numbers. Second, the all volunteer force is highly expensive. Conscription is a form of involuntary servitude, but I think it is an acceptable burden to place on a population in return for residing in this nation. We might not go all the way back to paying new conscripted Privates $78 a month as I recall was being paid when I went into the service, but likely would be only a fraction of what we have to pay to attract the all volunteer force.
