Review: If you want your faith in market forces and low taxation reinforced, this is a straightforward, but blinkered attempt to make you forget all about government regulation. Funny that west-European countries with bigger taxation and more government influence have less crime, better education, better health care, better TV programmes than the US. They also organise their politics better, so that the tax money is better spent. It did set me right on one or two points, and parts are written in a spuriously funny way, but it is too biased to be really informing . Clearly the writer has never listened to people he doesn't agree with.If you have an open mind compare this dangerous nonsense with the writings of Naomi Klein to see how unfettered capitalism works out in practice. 
 Polarity: Negative
True

Review: Where did the real Jack Higgins go? This is not only Higgin's worst effort to date, it is probably the worst book I've read in the past 5 years. (Can you say 'lazy', Jack?)I can't believe I actually finished it, and one star is a generous rating. Unbelievable chapter after unbelievable chapter, no character or plot development, written like a 5th grader.The end of the book foretells a sequel...a book that I will immediately pass on. Probably my last Higgins book without reading the reviews first.Don't buy it -- don't borrow it -- don't read it. 
 Polarity: Negative

True
