John Perkins wrote his interesting experience in his book 'Confessions of an Economic Hit Man' which says 'I also admit that my professors in university understand the nature of pure macro economy, that is in many things help grow the economy for only a few people who are on the top of piramide to become more wealthy, while the growing of the economy does not do anything for those who stay on the basic of piramide, they will only become poorer. Its true that putting Capitalism to prior will always cause a system which is like the feodal society in the middle age.'Should any of my professors know this, they would not admit it. Its probably because the big corporation and the stake holders who finance the university. By feeling the truth those professors would loose their jobs in other words feeling the secret should demand my sacrifation (John Perkins, 2005, P.30).
