For me, capitalism has never been an abstract concept. It is a real, concrete part of everyday life. When I was a boy, my family left the rural misery of Brazil's north-east and set off for São Paulo. My mother, an extraordinary woman of great courage, uprooted herself and her children and moved to the industrial centre of Brazil in search of a better life. My childhood was no different from that of many boys from poor families: informal jobs; very little formal education. My only diploma was as a machine lathe operator, from a course at the National Service for Industry.

I began to experience the reality of factory life, which awoke in me my vocation as a union leader. I became a member of the Metalworkers' Union of São Bernardo, in the outskirts of São Paulo. I became the union's president and, as such, led the strikes of 1978-1980 that changed the face of the Brazilian labour movement and played a big role in returning democracy to the country, then under military dictatorship.
