Bob, why don't you just read and respond to the article? You might actually learn something from it. And if you disagree with some of Heinberg's points, you can refute them here. And what, for that matter, are YOUR credentials? Just because you don't have any doesn't mean that no one ought to read your posts or take you seriously enough to respond. Judge an argument on its merit. Here is Heinberg's bio (as pdf), easily available on his web site: http://www.richardheinberg.com/sites/default/files/Richard_Heinberg_CV.pdf Having written eight books that have been translated into several languages, he has most certainly spent "time in front of a desk".
