Obama supports reduction in military retirement pay

So Obama supports changing military retirement to a 401k and saving 20 percent. The same time he opposes changing Social Security to a 401k like retirement program. Hum, something is not kosher here. If this works so well for military retirement why would we not want the same efficiency in our social security system? Not to mention the portability and personal ownership.
