Bureaucracy contrasts the two forms of economic management--that of a free-market economy and that of a bureaucracy.
In the market economy entrepreneurs are driven to serve consumers by their desire to earn profits and to avoid losses.
In a bureaucracy, the managers must comply with orders issued by the legislative body under which they operate; they may not spend without authorization, and they may not deviate from the path prescribed by law.
Ludwig von Mises here lucidly.
