production and/or management of a company condition workers to the company so that they will eventually follow the companys purposes faithfully. It leads them to play on the companys team. The ultimate reward is a better direct or indirect salary. For the company, it is reduced costs and higher productivity.Education becomes just a credential for hiring a worker. Its place in assessing the conditions of the candidate is secondary to work experience and professional competence. The latter are the key to an applicants success. The more the better. Education becomes only a necessary condition, but not sufficient. What is sufficient then? The sufficiency of experience and skills.Education as a credential and experience and skills as sufficiency are derived from the previous qualitative analyzes, the former theoretical and the latter observational. The theoretical analysis stems from the presentation and discussion of the P inequality measure and observational analysis from the experience of HR professionals. However, quantitative data on these dimensions are missing to anchor them in reality.The quantitative data will be included as information becomes available. IBGE itself does not have long series with comparable data. Methodological changes have altered these series - see section 6.1.4. The solution here was to find compatible series, or nearly so, even if from different sources, so as to be able to reach some conclusion regarding the relationship between workers education and income.Below are data from PNAD-Brazil for 2001 and 2011 on occupied people, by years of schooling, and the 2010 Census, by age groups, in absolute and relative magnitudes. Since, in general, age is taken as a proxy for work experience, that is, the higher an individuals age in the market, the more he has accumulated knowledge and skills, i.e. qualification, or skills. Tables 7 and 8 were used to compare with tables 5 and 6.Table 3 Occupied people (thousands), 10 years and more of age, by years of schoolingand monthly income classes of all jobs Brazil 2003ClassesWithout and -11 a 34 a 78 a 1011 a 1415 e +TotalAte 12186216072731116656117794412 a 12242232945332644234491141831 a 215742389651541215777373207492 a 3391770279119373855619103633 a 5173381156913503417125581455 a 104613058054420421567490910 a 2013361511576811235227320 e +3947452107331047Total63047651189171196418887589069613 Table 4 Occupied people (thousands), 10 years and more of age, by years of schoolingand monthly income classes of all Jobs Brazil 2011ClassesWithout and-11 a 34 a 78 a 1011 a 1415 e +TotalAte 12152910011953126887155667712 a 123551717446636545015364175711 a 22075178563156252126621526306152 a 35104141987206357161678123683 a 51881668569113468210476935 a 10716033640020772513545710 a 2020863804011238181020 e +831720107492647Total67565094159931464830317997082778Table 5 - Occupied people (thousands), (%), 10 years and more of age, by years of schoolingand monthly income classes of all jobs Brazil 2003ClassesWithout and -11 a 34 a 78 a 1011 a 1415 e +TotalAte 1223,420,234,414,77,10,210012 a 115,816,432,018,616,50,61001 a 27,611,531,419,927,81,81002 a 33,87,426,918,737,26,01003 a 52,14,719,316,542,015,41005 a 100,92,611,811,141,631,910010 a 200,61,66,66,930,054,310020 e +0,30,84,54,320,170,0100Table 6 - Occupied people (thousands), (%), 10 years and more of age, by years of schoolingand monthly income classes of all Jobs Brazil 2011ClassesWithout and -11 a 34 a 78 a 1011 a 1415 e +TotalAte 1222,915,029,419,013,00,810012 a 113,49,825,420,828,52,11001 a 26,85,820,620,441,45,01002 a 34,13,316,116,746,213,61003 a 52,42,211,111,845,127,31005 a 101,31,16,27,338,146,010010 a 201,10,43,54,422,268,410020 e +1,20,52,63,116,676,0100Source: PNAD Except without income and declarationThe idea behind the comparison
