Speaking as someone who receives his income in dollars, I hope US defaults. Maybe then people in US will finally start to give a second thought on the US military expansion all over the world, and the trillions of dollars it's spending on weaponry. There are a lot of domestic programs are that very wasteful, too - not just the police militarization ones, but also social ones.

Maybe this will make them look at every program from sub 100,000 in funding to the hundreds of billions of dollars. Almost $4 trillion in spending a year with a little over $2 trillion a year as income is simply unsustainable, no matter how you cut it. I think everyone can see that. As others mention, the default will happen eventually. It's just a matter of time, and the more it's delayed, the bigger the impact will be.

What worries me most, though, is that if an imminent collapse of the dollar will happen in the future because countries start dropping the dollar, out of desperation, US will start becoming a lot more aggressive in its bullying, and possibly even take military action against them for "hurting their economy", or at the very least use NSA surveillance to blackmail them into not doing so (my guess is that's already happening, though), and it's part of their "diplomacy" with those countries.
