The evolution of inequalities connected to incomes, wealth and capital ratio on income within the richest countries follows a U-shaped mathematical function. These analysis questioning this function, called Kuznets' curve that is connected to the hypothesis of a economic development able to mechanically produce a decrease in income disparities. Conversely, capitalism is characterised by strong powers of economic divergence, based on the inequality r g i.e. return on capital rate of economic growth. These elements emphasise how, within a society, growth is not connected to wealth becomes more important and belongs to a few. When the function is r g, the industrial development and production is heavily increased as is newly produced wealth. It is important to evidence the global governance and worldwide market role that influences development within different regions and countries. Giovanni Arrighi emphasised three phases to explain the economic and social dynamic crisis: the first is in the 19th century, the second is after the Second War World, the third is connected to the production of financial capital.
