They considered the development a gradual, continuous process and harmonious, derivative of the accumulation of different capital and of the Keynsian thought, the saving and the tax of interests saw the development to consist of its basic elements with. Historically, the neoclssicos had served to the economic policy of the capitalist countries until the 1929 crisis when then the development notion started to be on to the question of the income distribution. Mainly with Keynes the analysis fell on the macroeconomics of the full job with the State having for basic function the regulation of the economy, that is, different of the neoclssicos, Keynes its focus came back on the social stability in set with the economic one. Keynes then, believed that the economy would follow the way of the full job, being unemployment one moral-social 12 whose accumulation of wealth would not be given for the money accumulation and yes for the reinforcement of the currency.

Therefore, correct it is to affirm that Keynes was who in fact breached in the way to think the economy up to 1930, since, with the General Theory of the Job, the Interest and the Currency, 1936 14; the development if return now for the accumulation of monetary force and more on the form of accumulation of real goods and from there the necessity of the State not to come to intervine directly in the economy. Keynes thus, if worried about the human being-social perfectioning, but above all, if he worried about the capitalist reform. .
