The bread line of the great depression.
A great bit of contradiction.

Are we headed for the same thing all over again?
The rich would probably like that.

Well if you're asking about the income gap. We're already there, the income gap currently is the greatest since the great depression.

I kind of see all the symptoms - decline of the middle class (thanks to the sub-prime housing market), unprecedented stock gains etc.

However I'm no economist, someone more knowledgeable might answer your question better.

high debt to income ratios,
American dollar losing value,
real estate bubble bursting,
high levels of corporate corruption,
crooked credit card and predatory lenders

shall I go on?

Oh and 0.7% Economic Growth and reasonably high inflation (Compared to the GDP growth)

This famous photo was taken in 1937. These people are flood victims in Louisville, KY. The Ohio River flooded its banks that year. They are in line for emergency food aid. Not precisely "bread line of the Great Depression."

Going downhill is hard to swallow....
When your flag-wavers stop waving
.... and start fainting from hunger
.....and dying like flies in foreign wars,
where all the tax mony has gone,
instead of going to social services....
Easy come, easy go....
Sure no way likethe American way....
