Many of the undergraduate books on economics show cynical cartoons and in other places too, this subject is treated in a trivial and facitious manner. It is as if the writers cannot properly understand how to explain the phenomena and are using the cynical joke to get over their inadequacy. This is a big mistake. How are the managers of our national economy supposed to make their decisions with all the hoopla and distractions of this claptrap? Taxation is a serious matter and surely deserves a better treatment than this kind of twaddle. The writer has developed a unique and general method of understanding how the general macroeconomics system works based on engineering principles in the most logical and watertight manner. The results are surprising for those who are unable to grasp the basic idea that macroeconomics should be examined from sufficient distance so as to cover everyones point of view and not based on individual preferences. The method shows the fact that any kind of taxation stimulates the economy but due to the topology of the social connection between it various functions, the taxation of land values is 3 times more effective that taxing incomes.
