The workers should take over the factories, and shut down Boeing's profit-making machine.

When the New Deal programs were passed in the mid 1930s, millions of workers were joining unions, striking, and occupying factories to fight for a better life. It was this radical labor movement that forced the establishment to make concessions.

Bernie Sanders says that the biggest banks that dominate the economy should be broken up into smaller banks. This would be far more radical than Hillary Clinton's proposals to regulate Wall Street.

Whether or not you agree with Bernie Sanders' version of socialism, it is enormously significant that, for the first time in US history, a presidential candidates who calls himself a socialist has had an actual shot at winning the presidential election.
