From the article:
Yet a much larger threat to an effective U.S. military is the influx of conscripts into the force. Let the progress provided by data-driven standards serve as a catalyst for the next iteration of a market revolution in military recruitment and personnel management, and take Selective Service off of the table.
Pretty good article. The author alludes to the growing rift - "Proponents of the draft rightly highlight the growing divide between the nation and the force that defends it. This civil-military divide has pernicious effects on decisions regarding the use of military force." This, I suspect, is an even more root problem than Selective Service.
