Cleaners useful bankers

Than the famous British scientists? First of all, the fact that the conduct or useless research or study, whose findings were clear and without research. However, sometimes, among the fruits of their violent activities occur very amusing. For example, recently, British scientists from the center of analysts New Economics Foundation found that nannies or cleaners bring to society far more useful than the bankers. Moreover, the financial impact of work they are also superior to the bankers. Russian researchers confirm the findings of British colleagues and dismayed at the Russian specificity of the same problem. According to Boris Kagarlitsky, Director of the Institute of Globalization and social movements, we have the ratio of managers and their salaries are in a completely wild imbalance in the number and salaries of employees, producing material product.

British offer to solve the problem of equalization of wages, on the basis of social benefit brought by the profession. But here, in terms of Russian experts, spit found on a stone, because the exact number of required country cleaners can be, and how to determine the number of required banks and bankers?
