You could always apply to become part of the EMU, however, since your economy hasn't been good enough to even get close for the last 5 years they probably wouldn't accept you.
Greece is in the shitter because they need to adjust to the EMU rules, all in all, they have less of a debt than the US will have in the next 20 years regardless of what happens now.
Thing is, the EMU was good at tightening things up for nations within it, the US just ran with debt when you had the chance to fix your finances and now that you're in the shitter, you are REALLY in the shitter.
Even if things change, you'll still be in the shitter while the rest of the world is free to spend.
You do realise who is to blame for that?
