From 2003 to 2016, he was National Secretary of Solidarity Economy, where he worked in close collaboration with the FBES (Foro Brasileiro de Economia Solidaria) and where he defended, among others, the creation of community banks as an instrument for the eradication of poverty.

In the month that Paul Singer completed 86 years, the book “Ensaios sobre Economia Solidária” organized by Rui Namorado of Editora Almeidina was launched in Portugal. The book integrates a theoretical perspective of solidarity economy, which values ​​its historical depth, with its anchorage in Brazilian reality. It is divided into two parts, each of which comprises eight texts. The first is predominantly constituted by essays in which Singer shows how he conceives solidarity economy theoretically, valuing it as a struggle against the exclusion of the exploited and as a possible emancipatory opportunity, towards a future that consubstantizes full humanism. The second one leads us through experiences of the solidarity economy in Brazil, in interaction with the political position of Singer, as a member of the federal government, taking as a backdrop his fraternal closeness with the organizations involved.
