Military pay might pay for itself

I was just reading this article over on NRO and had a bit of an epiphany.
Why not immediately double the pay of all military personnel?
A few restrictions, though. While we would accept the current obligations of those in the service as valid, any new recruit or any re-up would be a ten-year obligation; period, end of subject, only way out is to get killed or become permanently disabled or do something stupid that earns you a dishonorable. But after 10 years you could retire on half pension; after 20, full pension.
And at the same time we do this, welfare gets cut to subsistence levels. The message: Serve your country and make a decent living. Choose to sit on your duff, and you can just get by while you’re looking for a job.
If we’re really committed to a strong national defense and a years-long war on terror, we need recruits. And they should be paid enough to make joining up worthwhile. In turn they should be willing to serve for a longer period. And let’s face it, under this plan joining at 18 and reupping once gets you to 38 and a full pension; technically you could sit on your butt for the rest of your life. (Few probably would.)
I would have joined up 25 years ago for a deal like that. Instead I’m still a wage slave at 43. Ah well.
