The issue of social classes
This issue of social classes is not very well analyzed according to my opinion. 1) in all parts of the world there are at least three social classes: the poor, the middle class and upper class, 2) the only countries that have made these three classes are not presented with substantial gaps or distances are the Nordic countries ( Sweden Filalndia, Denmark and Norway), 3) in the U.S. are the poor in urban slums typically reside colored population, 4) in Europe's poor live in the outskirts of large cities, 5) in Latin America is where there is a very obvious gap among the three social classes and even within the class of poor people living in slums like the slums of Rio and the Caracas Ranchos, there is another class those with extreme poverty, 5) Africa is a case very special, because the vast territorial extesnion class exists very poor and extreme poverty levels frightening.
The poor in the Nordic countries are similar to the middle class in Latin America. In Latin America there is a middle-middle class and professional middle class and the rich or wealthy families that do not match the real rich and developed countries, where if there are even billionaires.
But the urban poor can be classified into: a) the urban poor who were born and became part of his neighborhood, b) the urban poor who migrated from rural areas in search of employment in urban areas and formed their neighborhoods that began with houses of cardboard and waste and in 50 years managed to transform, with their savings, homes in seeing these blocks and moldings, but without any plan or government help and so they formed a chaos of living quarters, attached to each other; c) the poor who remained in rural villages and small geographic areas with their own crops and poultry (with better quality of life that the urban poor).
There is a social gradient in Latin America, transforming the slums, the Ranchos, the slums, the Cayampas, Mexican Slum, in areas with more orderly comprehensive refurbishment program of those living spaces, where the community college has very close of children, the primary health center, plazas and sports facilities for recreation, other spaces for educational and cultural amenities, and even religious.
It is more important to a well-developed remodeling of urban space invaded, that the construction of new housing or relocation of these populations in rural areas again (programs that have failed because they return to the field can not be done in an improvised manner and that real reform and agricultural agragia only be achieved with credits, technical assistance and comprehensive planning as what has been accomplished by Israel in its Kibus example, or the small farmers in the U.S., or rural district in Spain, and Italy Fracia.
In the Nordic countries and Austria also, considered the country with better living standards, it has taken them a long time to achieve better development opportunities and wealth distribution. It is impossible to bridge the social gaps if a country does not produce wealth, and if that wealth is not well managed and setting priorities (housing, education, health, employment and adequate social benefits with fair). The advantage of the Nordic countries and also Switzerland, which are small geographic areas, of course is more complicated to achieve the distribution of wealth in China and India, as are countries with many people in vast geographic areas.
