According to sociologist Marcelo Ridenti, Brazilian politics is divided between internationalist liberals and statist nationalists. The first group consists of politicians arguing that internationalization of the economy is essential for the development of the country, while the latter rely on interventionism, and protection of state enterprises. According to Ridenti, who cites the Fernando Henrique Cardoso administration as an example of the first group and the Luiz Inácio Lula da Silva administration as an example of the second, "we have it cyclically".
