@McReggae and @Kyt, I beg to differ.
Ponder the fact that big parameters exist for the defination of the "Middle Class in Kenya, as elucidated in the above link.
In as far as I have a paper to sit for and I have based my argument on Barbar Ehrenreich's thesis, would you give me a fail if I asserted that a Middle Class does indeed exist in Kenya, based on the following?
Barbara Ehrenreich and her husband John defined a distinct part of the middle class in 1977 as "salaried mental workers who do not own the means of production and whose major function in the social division of labor is the reproduction of capitalist culture and capitalist class relations".
The Ehrenreichs named this group the "professional-managerial class". This group of middle-class professionals are distinguished from the rest of the class by their training and education (typically business qualifications and university degrees), with example occupations including academics and teachers, social workers, engineers, managers, nurses, and middle-level administrators.
The Ehrenreichs developed their definition from studies by André Gorz, Serge Mallet, and others, of a "new working class", which, despite education and a perception of themselves as being middle class, were part of the working class because they did not own the means of production, and were wage earners paid to produce a piece of capital.
The professional-managerial class
seeks higher rank status and salary, and tend to have incomes above the average for their country
