"Capital in the 21st Century" is based on the bestselling 2013 book by Thomas Piketty, a French economist. The film, directed by Justin Pemberton, undermines that core power of the world's elites " shaping how we think " in a particularly wise, sneaky way. The movie starts by going back to the ... Industrial Revolution. Both the American and French revolutions were in part fights between old feudal elites and a new business elite struggling to be born. And while the old and new elites disagreed on who should be in charge, they both agreed that regular people shouldn't be. By 1914 in Paris, the top 1 percent owned 70 percent of all wealth, and two-thirds of the population died with nothing. In the face of this raw brutality, all kinds of alternatives, from communism to socialism to Georgism, gained adherents across Europe. Capitalists were petrified. What could they do that wouldn't require them to share any wealth or power? "You have this rise in nationalism and competition between European countries," Piketty says. "Nationalism is often used by elites to make people forget class conflict and instead focus on national identity." It was only with the worldwide slaughter of the Second World War that capitalism was willing to make some changes. But as World War II receded into the distance, capitalism mounted a counterattack with the elections of Ronald Reagan in the U.S. and Margaret Thatcher in the U.K.
