Earlier in the day, Walesa joined Grzegorz Ekiert, Laurence A. Tisch Professor of Government and director of the Minda de Gunzburg Center for European Studies (CES), students and faculty from Poland, and those interested in Eastern Europe for a freewheeling discussion at CES about political and economic issues in contemporary Poland and Europe.

While populist movements across Europe, and even in the U.S. with the rise of Donald Trump, have accurately identified the socioeconomic problems brought about by the global economy, he said the solution is not to eliminate free markets, break up Europe, or sever Western alliances. Rather, liberal democracies, which Walesa said he was “very, very hopeful” will include the U.S., must work together to come up with a type of capitalism that works for the 21st century, one in which workers and owners share in a company’s success.

Working at the Lenin shipyard in Gdansk, Poland, during the 1970s, Walesa became an unlikely political and social activist, leading 17,000 striking workers to form the trade union Solidarnosc, or “Solidarity,” in 1980. The union, created to bargain with the Soviet-controlled government for better wages and working conditions, soon became a global, nonviolent protest movement against Communism and in favor of democracy and workers’ rights.

Walesa was awarded a Nobel Peace Prize in 1983 for his work, and his movement was credited with speeding the fall of Communism, which began in 1989 with the fall of the Berlin Wall. In 1990, Walesa won a landslide electoral victory, becoming the first president of the newly democratic Poland. He served until 1995.

Now 76, Walesa had been enjoying retirement, but the developments in Poland and Europe, particularly the resurgence of populist and nationalist politics, prompted him to go back out on the field, he said.

“You have to do everything you can, and I’m promising that I will contribute as much as I can for the United States to restore its leadership position in the world,” he told the gathering at HKS.
