The book is loaded with various economic sophisms from areas such as price ceiling, subsidies, rent control, minimum wage etc., where policies catered to small special economic group appear beneficial to such groups in the short term but end up bringing much unwanted ills to the whole population in the long term - there are Seen and unseen effects of all economic policies. But the author's language is a mix of strong logical arguments mixed with emotional ones, so in some places I feel he leads you astray with some of his reasoning. He also seems to have such fundamental and deep belief in free markets which only works efficiently if all actors participating in such markets have all the information readily available to them. In almost all arguments this is taken as the ground reality. Very anti-Keynesian and propounds libertarian principles. But still this book is a solid introduction to economics.
