What percent of the world population do farmers constitute?

The Working class in the United States is roughly as vaguely defined as the middle class with which it overlaps according to some definitions. While some might argue that the working class is synonymous with the lower middle class, it may also be argued that the working class constitutes the majority of the American population (aka: the Silent majority). A distinctive feature of this class may include that fact that workers from this class merely take orders and are neither compensated for their ideas nor are they involved in the decision making process of the organization for which they work. Yet another, more dated, definition is that the working class commonly consists of blue-collar workers, while non-professional white collar workers are lower middle class. The guideline stating that working class workers are not paid to think but rather carry out tasks persists however, through many different ideologies regarding this class. If sees as the majority, the working class may also be sub-divided as done so by Paul Fussel who uses the Marxist terminology referring to the working class as proletariat, differentiated between the High-proletarian, Mid-proletarian, and Low-proletarian. Much like the lower middle class (which may be the same class according to some theories) the working class has little economic security and is extremely susceptible to fluctuations in the economy. Currently out-sourcing and cost-cutting related lay-offs are much more a pressing issues for persons of this class, than in the higher classes.
