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 S?o 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 S?o Bernardo, in the outskirts of S?o 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.

The impact of the union movement on Brazilian society led us to create the Workers' party, which brought together urban and rural workers, intellectuals and militants from civil society. Brazilian capitalism, at that time, was not only a matter of low salaries, insalubrious working conditions and repression of the union movement. It was also expressed in economic policy and in the whole set of the government's public policies, as well as in the restrictions it placed on civil liberties. Together with millions of other workers, I discovered it was not enough merely to demand better salaries and working conditions. It was fundamental that we should fight for citizenship and for a profound reorganisation of economic and social life.
