@roger,
And I hope that someday the lion will lie down with the lamb.
We will see the sort of spending cuts we need when there is no other choice, which means we will be in Greek Mode. Still there will be the shrill voices on the Left screaming that austerity is death; we need to keep spending. Undoubtedly, we will also see Greek Mode street riots by folks who can't imagine life without another governmental fix, and who are only too willing to believe the progressive demagogues telling them is more money to be had if they just lynch the rich.
We haven't seen even a fraction of the worst with Greece because they are among the first and only a nit. When the US hits the skids, there will be no one to bail it out.
I have no more faith in American Democrats or Republicans than I do in Greek politicians, because I don't have a lot of faith in a very large segment of the American population. As long as The Takers can swing elections, we will have politicians catering to them...just like in Greece.
At this point the question is how long before this happens, not if it will happen.
Unfortunately the good things we expect from the future always take long to materially than we expect, while the bad things rush in on our predictions.
We'll hit rock bottom long before we have flying cars.
