This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.

Ex Output:
Positive

I guess I didn't find this CD memorable, as I couldn't even remember what it sounded like. There were no particular pieces that jumped out at me and cried "Dance to me." Overall I was not that impressed.

Ex Output:
Negative

Good stuff from the great freedom fighter. Rarely known texts are included with the famous "Narrative." "The Condition of the Freedmen", a look at African-Americans 20 years after the end of slavery, provide some sobering thoughts for American Blacks today. "The Heroic Slave" tells the little-known true story of Madison Washington, who led a slave ship called "The Creole" into freedom in 1841. I would also recommend "The frederick Doulgass Reader" and "The Life and Times of Frederick Doulgass" to make your "Dougology" complete!
