Black Swan:   I have noticed too, how insulting the commentators are.   How it passes civility, I don't know.   Putting the imperfections of the leaders aside;   I think the number one thing that will affect economics more than anything:   I thought trade barriers in 1930, should have provided some knowledge to the American people about economic depression.   It took a decade to recover.   And Black Swan, I appreciate your complements and decorum, whether good, bad or ugly.
