Today is different ...
I think the U.S. economy will be okay in a year or two. Congress will put some mildly effective controls into place so that this exact same thing won't happen again and people's confidence will go back to relative normal. And the U.S. economy can once again be strong (though all the while very slowly eroding in it's position as THE world economy; but that will probably take many years). All this should come to pass so long as the average American doesn't panic. Because when they don't panic; they keep spending money and keep the economy going.
But if Mr. and Mrs. Average American panics, stops spending and takes their monies out of financial institutions (because they don't trust that their monies are safe); then the shit will really hit the fan and a depression is very likely (though for not nearly as long as the 30's one).
Solid economies are all about (imo) keeping people from getting too rich or too poor and ALWAYS keeping consumer confidence relatively high.
Today is different.
We're not the pure capitalist society like we were in the '20s through early '30s.
As I said, we're moving from facist to socialist.
Which means people just need to get used to the US GDP being 50% of what it was.
And 10% unemployment will be the norm, instead of sub-5%, but nothing like the 25% of the Depression.
The medical industry as a profit option is going to be the next casualty.
Sorry to all those doctors and companies who thought otherwise, their money is going to be tied up.
