IIRC, if they just stop "fixing" the Alternative Minimum Tax, and just leave it where it is, and also don't extend any of the tax cuts that were supposed to have expiration dates, the U.S. deficit would disappear within a decade. Dire predictions of exploding debt are based on the (sadly justified) assumption that irresponsibile politicians will keep extending tax cuts and keep raising the requirements for the AMT to apply. And, of course, they could cut three quarters of the defense budget and still be spending much more than the U.S. needs to defend itself. They'd have to stop wasting money on pointless and unprofitable foreign wars, but as someone with a friend in the U.S. military, I'd rather she be looking for a job than risking her life for no good reason (and that's what she'd prefer too, as it happens).
