Do y'all think the it has done more harm then good in the world?and do y'all think there is any truth to the book confessions of an economic hitman by john perkins
Economics is like psychology, its not an exact science. So no, there is no truth to it, its just a best guess.
It isn't a science at all. It is social analysis. There are a few universally accepted things in it such as the law of supply and demand. But not many. It is basically a collection of opinions, most of which compete with one another.
