I think national budget is better determinant of middle class, since it shows the money in compare to money out, and how large the deficit or surplus if found. If the deficit is so high, let's say 15-20 percent to the GDP, IT IS WISHFUL THINKING TO DISCUSS WHETHER THRERE is a middle class in that country. Access to health and education are very significant variables. Demographic status, hether the country is youthful, transitional, mature and aging are to beconsidered also. I would say that most social issues and phenomenon are place base rather than people base, and this applied to middle class within the country.
